[0052] The upper box body 5 is a transparent square frame and is covered on the top of the lower box body 2 to form a sealed containing box with the lower box body 2. A circle of sealing ring can be set at the top opening of the lower box body 2 to improve the sealing effect; two lifting devices 6 are vertically and symmetrically arranged on both sides of the containing box formed by the upper box body 5 and the lower box body 2, and the two ends of the lifting device 6 are fixedly connected to the outer wall of the lower box body 2 and the outer wall of the upper box body 5 at the corresponding ends through connecting plates; a rotating liquid adding mechanism is arranged on the upper box body 5, which is used to add reaction liquid to the reaction bottle.

[0055] The rotary liquid adding mechanism comprises a servo motor 7, a rotating disk 8, a cam 10, a rotating rod 14 and a liquid adding device.

[0056] The servo motor 7 is arranged at the top center position of the upper box body 5. The servo motor 7 can be electrically connected to the controller in the control box 1 through a spring wire and a plug arranged at the end of the spring wire. The action of the servo motor 7 is controlled by pressing the corresponding control button, and the time interval and rotation angle of each forward and reverse rotation of the servo motor 7 can be set according to needs; the execution shaft of the servo motor 7 is vertically arranged downward and extends into the upper box body 5, and the execution shaft of the servo motor 7 is rotatably connected to the upper box body 5; the turntable 8 is horizontally arranged at the end of the execution shaft of the servo motor 7 and two arc plates 9 are vertically and centrally symmetrically arranged on both sides of the turntable 8, and the two arc plates 9 deviate from the horizontal center line of the turntable 8 by a certain distance.

[0057] The cam 10 is an elliptical structure with both sides extending outward, and the cam 10 is sleeved on the actuator shaft of the servo motor 7 located in the upper box body 5. A plurality of fixing rods 11 fixedly connected to the bottom of the top plate of the upper box body 5 are arranged on the cam 10; an elliptical annular groove 12 is arranged around the cam 10, and elliptical slideways 13 are correspondingly arranged on the upper and lower sides of the inner side of the cam 10 located in the annular groove 12.

[0058] Two rotating rods 14 are horizontally and symmetrically arranged on both sides of the cam 10, one end of the rotating rod 14 extends into the annular groove 12 on the corresponding side and positioning slide columns 15 extending into the corresponding slideway 13 are arranged above and below the rotating rod 14; the other end of the rotating rod 14 is inserted through the corresponding arc plate 9 and a fixing clamp 16 is arranged at the end of the rotating rod 14, and the fixing clamp 16 extends to above the reaction bottle 4 on the corresponding side; when the rotating rod 14 is located on both sides of the cam 10, the rotating rod 14 has a certain inclination angle relative to the horizontal center line of the turntable 8.

[0059] The fixing clamp 16 includes two symmetrically arranged Ω-shaped clamps 36, and corresponding threaded holes are opened on both sides of the two clamps 36. One side of the clamp 36 is fixedly connected to the end of the rotating rod 14, and the other clamp 36 is fixedly connected to the clamp 36 fixed to the end of the rotating rod 14 through a bolt assembly; in order to prevent damage to the liquid charger, a rubber pad is also attached to the inner side of the clamp 36.

[0060] The two liquid adders are centrally symmetrical, and two semi-elliptical slide grooves 17 with openings facing toward the sides close to each other are symmetrically arranged on the front and rear end plates of the top plate of the upper box body 5. The slide grooves 17 are located on the outer side of the turntable 8 and the size of the slide grooves 17 can be designed according to the sizes of the turntable 8, the cam 10 and the rotating rod 14. The liquid adders vertically penetrate the corresponding slide grooves 17 downward and extend into the upper box body 5. The lower end of the liquid adder is fixed by a fixing clamp 16.

[0061] The rotary liquid adding mechanism further comprises a buffer spring 18 , and two buffer springs 18 are respectively sleeved on the rod body of the rotating rod 14 located between the arc plate 9 and the corresponding side cam 10 .

[0062] When the servo motor 7 drives the turntable 8 to rotate, the turntable 8 will drive the rotating rod 14 to rotate synchronously. Since the cam 10 is fixed in the upper box body 5 by the fixing rod 11, when the turntable 8 drives the rotating rod 14 to rotate, the end of the rotating rod 14 extending to the annular groove 12 on the cam 10 can only move along the slideway 13 under the restriction of the positioning slide post 15. In the process of the rotating rod 14 moving from the two sides of the cam 10 to the front and rear ends of the cam 10, the distance between the side wall of the cam 10 and the arc plate 9 is continuously increased, and then under the limiting action of the cam 10, the liquid charger will be pulled to move toward the side close to the arc plate 9; similarly, in the process of the rotating rod 14 moving from the front and rear ends of the cam 10 to the two sides of the cam 10, the distance between the side wall of the cam 10 and the arc plate 9 is continuously shortened, and then under the limiting action of the cam 10, the liquid charger will be pushed to move toward the side away from the arc plate 9, so that the humidifier can move in the corresponding slide groove 17.

[0063] The liquid charger comprises a liquid charging cylinder 19 , a piston 22 , a pumping rod 23 , a top plate 24 , a fixed side plate 25 , a mounting plate 27 and a telescopic device 28 .

[0064] A liquid discharge head 20 is provided at the bottom end of the liquid adding cylinder 19, a top ring 21 is provided at the top of the liquid adding cylinder 19, and scale lines are also provided on the liquid adding cylinder 29; the piston 22 is slidably arranged in the liquid adding cylinder 19 and fits with the inner wall of the liquid adding cylinder 19; the pumping rod 23 is vertically arranged downward and inserted into the liquid adding cylinder 19 and fixedly connected with the piston 22; the top plate 24 is arranged on the top of the pumping rod 23; the liquid adding cylinder 19, the liquid discharge head 20, the top ring 21, the piston 22, the pumping rod 23 and the top plate 24 form a structure similar to that of a syringe, and its working principle is the same as that of a syringe.

[0065] Two fixed side plates 25 are symmetrically arranged on both sides of the top ring 21 and a column 26 is vertically arranged on the top of each fixed side plate 25; the mounting plate 27 is horizontally arranged on the top of the column 26; the telescopic device 28 is arranged on the top of the mounting plate 27, and the execution axis of the telescopic device 28 vertically penetrates the mounting plate 27 downward and is fixedly connected to the top plate 24.

[0066] The telescopic device 28 can be electrically connected to the controller in the control box 1 through a spring wire and a plug arranged at the end of the spring wire. The servo motor 28 is controlled by pressing the corresponding control button, and the execution axis of the telescopic device 28 contracts, and the reaction liquid can be sucked into the liquid adding cylinder 19 through the liquid outlet head 20; the execution axis of the telescopic device 28 is extended, and the reaction liquid can be pushed out through the liquid outlet head 20; the telescopic device 28 can use a servo electric cylinder, and the time interval and the stroke of each extension of its two telescopic devices 28 can be set, so that the execution axis is pushed downward a certain distance after the liquid adder moves to the top of the reaction bottle 4, and the reaction liquid in the liquid adding cylinder 19 is injected into the reaction bottle 4. Controlling the action of the servo electric cylinder is a prior art and will not be repeated here.

[0067] The safety detection device further includes an exhaust pipe 29 , an exhaust fan 30 and a top cover 31 .

[0068] The exhaust pipe 29 is arranged on the outer side of the rear side wall of the lower box body 2 and is connected to the interior of the lower box body 2; the exhaust fan 30 is arranged on the outer side of the rear side wall of the lower box body 2, the air inlet end of the exhaust fan 30 is connected to the exhaust pipe 29, and the air outlet end of the exhaust fan 30 is connected to the outdoors through a hose. The exhaust fan 30 is electrically connected to the controller in the control box 1, and the operation of the exhaust fan 30 is controlled by pressing the corresponding control button.

[0069] The top cover 31 is a transparent square frame and is covered on the top of the upper box body 5. A square groove 32 is provided on the top of the upper box body 5 for inserting the bottom end of the top cover 31; wiring grooves 33 are provided at the lower sides and the lower rear side of the top cover 31; and a handle 34 is provided on the top of the top cover 31.

[0070] In actual application, a certain amount of different types of reaction liquids are first sucked into the liquid adding tubes 19 of the two liquid adding devices, and then inserted into the upper box body 5 from above, and the liquid adding tubes 19 are clamped by the fixing clamps 16, and then the upper top cover 31 is installed; then the reaction bottle 4 containing a certain amount of hazardous chemicals is placed on the corresponding magnetic stirrer 3, and then the lifting device 6 is pressed to shrink the execution axis, driving the upper box body 5 to move down and fit with the lower box body 2 to achieve sealing.

[0071] Then start the magnetic stirrer 3 and the exhaust fan 30, and then start the telescopic device 28, so that the execution shaft of the telescopic device 28 extends out, and the reaction liquid is pushed out to the reaction bottle 4 located below it through the liquid outlet head 20. The execution end of the telescopic device 28 stops moving after extending a certain distance; then start the servo motor 7, and the servo motor 7 will drive the turntable 8 to rotate a certain angle in one direction, so that the liquid adder moves to the top of another reaction bottle 4. Since the time after the servo motor 7 rotates to a fixed position is fixed, the time interval of each action of the telescopic device 28 can be determined according to the time of one rotation of the servo motor 7. After the liquid adder moves to the top of another reaction bottle 4, the execution shaft of the telescopic device 28 extends out, and the reaction liquid is pushed out to the reaction bottle 4 located below it through the liquid outlet head 20. The execution end of the telescopic device 28 stops moving after extending a certain distance, and then different reaction liquids are added to the two reaction bottles 4; then the servo motor 7 rotates in the opposite direction to a fixed position to add liquid, and this cycle is repeated until the reaction liquid is quantitatively added to the two reaction bottles 4 and then stops. During the process of adding the reaction liquid, the detection personnel can observe the state changes in the reaction bottle 4 outside the box.

[0072] In order to control the time of adding the reaction liquid so as to facilitate the inspector to stop adding the liquid in time, the liquid addition time can be set on the timer 35 at the beginning of the first liquid addition. After the set time is reached, the timer 35 alarms to remind the inspector to stop adding the liquid.

[0073] In summary, the present invention provides a safety detection device for hazardous chemicals, which adds different reaction liquids into two reaction bottles at certain time intervals by rotating the liquid adding mechanism, thereby reducing the labor intensity of detection personnel, avoiding excessive participation of detection personnel in the detection experiment process, and reducing operational risks; the exhaust fan and the top cover can prevent the volatilization of hazardous chemicals, which may endanger the personal safety of detection personnel and reduce safety hazards.

[0074] The above is only a preferred implementation of the patent of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the patent of the present invention. These improvements and modifications should also be regarded as the scope of protection of the patent of the present invention.
