[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-3, An embodiment provided by the present utility model: A water quality sample storage device for environmental detection, including a storage box 1. On the left and right sides of the inner wall of the storage box 1, there are sliding blocks 16 slidably connected. The opposite ends of the sliding blocks 16 are fixedly connected together with a sliding frame 6. A plurality of vertically penetrating test tube placement holes 8 are evenly opened on the inner wall of the sliding frame 6. At the center of the inner wall of the sliding frame 6, there is a lifting screw rod 9 threadedly connected. The bottom end of the lifting screw rod 9 is rotatably connected to a wind guiding seat 12. A through groove is opened on the bottom inner wall of the storage box 1 corresponding to the bottom end of the wind guiding seat 12. A porous rubber pad 10 is fixedly filled on the bottom inner wall of the storage box 1 corresponding to the outside of the wind guiding seat 12. At the four corners of the bottom of the storage box 1, there are support legs 5 fixedly connected. On the left and right sides of the front and rear outer walls of the storage box 1, there are lifting belts 3 rotatably connected. On the left side of the top of the storage box 1, there is a box cover 2 rotatably connected. On the right side of the top of the box cover 2, there is a handle fixedly connected.

[0027] Specifically, the sliding frame 6 can stably slide up and down on the inner wall of the storage box 1 under the rotation of the lifting screw rod 9 and the guiding action of the sliding blocks 16. The lifting screw rod 9 is made of alloy steel material, which is sufficient to support the weight of the sliding frame 6. The size of the test tube placement holes 8 is larger than all sample storage test tubes on the market during actual production. The wind guiding seat 12 is used to support the lifting screw rod 9 and is communicated with the outside through the bottom through groove. The multiple holes in the inner wall of the porous rubber pad 10 communicate with each other. When the test tube is placed on it, the bottom will remain stable under the action of frictional resistance. The tops of all the test tubes used will be sealed with a rotary piston. The support legs 5 facilitate the through groove not to contact the ground, thus facilitating air circulation. The lifting belts 3 facilitate lifting the storage box 1 from both sides, which is convenient for carrying. The box cover 2 can be lifted and opened through the handle, and there is also a lock hole beside the handle to facilitate locking the box cover 2 to close the top of the storage box 1.

[0028] Referring to Figure 4 , at the middle of the front end of the clamping push plate 15, there are arc-shaped plastic clamping plates 13 fixedly connected. On both sides of the test tube placement holes 8 on the inner wall of the sliding frame 6, there are arc-shaped grooves 17 that penetrate forward. The shapes of the left and right sides of the rear end of the arc-shaped plastic clamping plate 13 are respectively fitted with the shapes of the inner walls of the arc-shaped grooves 17. On the left and right sides of the front end of the clamping push plate 15, there are springs 14 fixedly connected. The front ends of the springs 14 are fixedly connected to the inner wall of the sliding frame 6. At the top of the inner wall of the sliding frame 6 corresponding to the top of the clamping push plate 15, there are threaded tightening rods 7 threadedly connected. The tops of the threaded tightening rods 7 all penetrate the outer wall of the sliding frame 6, and the bottoms of the threaded tightening rods 7 all penetrate the inner wall of the sliding frame 6 and are in close contact with the top surfaces of the corresponding clamping push plates 15.

[0029] Specifically, both ends of the arc-shaped plastic splint 13 will be inserted into the corresponding jacks of the arc-shaped groove 17 under the pushing action of the clamping push plate 15, so as to cooperate with the other end of the placement hole 8 to stably clamp the outer walls of test tubes with different diameters. The spring 14 is in a compressed state in the figure, and in a completely relaxed state, most of the arc-shaped plastic splint 13 can be inserted into the arc-shaped groove 17. The threaded tightening rod 7 limits the clamping push plate 15 by the pressure exerted on the clamping push plate 15 through downward tightening. The length of the clamping push plate 15 will not cause the threaded tightening rod 7 to disengage from the top of the clamping push plate 15 during the downward rotation process.

[0030] Referring to Figure 1 and Figure 5 , in the middle of the top end of the inner wall of the air guide seat 12, a heating motor 20 is fixedly connected. At the bottom end of the heating motor 20, a conical electric heating block 19 is fixedly connected. In the middle of the outer wall of the air guide seat 12, an annular ventilation window 21 is opened. At the bottom end of the air guide seat 12, it is fixedly connected to the middle of the bottom end of the inner wall of the storage box 1. On the right side of the inner wall of the storage box 1, near the porous rubber pad 10, a temperature sensor 11 is fixedly connected. At the bottom of the front outer wall of the storage box 1, a controller 4 is fixedly connected. Both the heating motor 20 and the temperature sensor 11 are electrically connected to the controller 4. The outer wall surface of the air guide seat 12 does not contact the inner wall of the porous rubber pad 10.

[0031] Specifically, the electrical connections between the temperature sensor 11, the heating motor 20 and the controller 4 are connected through internal wires. The controller 4 controls the start of the heating motor 20 through corresponding PLC programs. The positions of the annular ventilation window 21 and the conical electric heating block 19 are parallel to each other.

[0032] Working principle: First, after obtaining an environmental water quality sample, the obtained sample water is placed inside a sample storage test tube. Then, the top door 2 of the storage box 1 is opened through structures such as the handle and keyhole on the door 2. Next, by rotating the lifting screw rod 9, the sliding frame 6 slides up and down on the inner wall of the storage box 1 to a suitable position, facilitating the limiting of the outer wall of the sample storage test tube at an appropriate height. Then, when a certain sample storage test tube needs to be stably placed inside the inner wall of the storage box 1, first rotate the threaded tightening rod 7 adjacent to the corresponding test tube placement hole 8, so that the clamping push plate 15 at the corresponding position of the sliding frame 6 cancels the limit. Then, the sample storage test tube is passed through the extrusion of the arc-shaped plastic clamping plate 13 to make it squeeze the clamping push plate and compress the spring 14 to contract into the inner wall of the sliding frame 6, so that the middle part of the sample storage test tube body is clamped between the inner wall of the sliding frame 6 under the action of the arc-shaped plastic clamping plate 13 and the inner wall on the other side of the placement hole 8. Then, rotate the threaded tightening rod 7 again to limit the position of the clamping push plate 15, thus facilitating the stable clamping and fixing of sample storage test tubes with different diameters. After the sample storage test tube is placed inside the inner wall of the sliding frame 6, its bottom will be in close contact with the porous rubber pad 10, so that the sample storage test tube will be limited both at the bottom inside the storage box 1 and in the middle part of the tube body, thus stably placing different sample storage test tubes inside the storage box 1 without affecting each other. When taking out a certain sample storage test tube, just unscrew the threaded tightening rod 7 at the corresponding position. Secondly, when the sample storage test tube is placed on the inner wall of the storage box 1, the internal temperature sensor 11 can monitor the temperature of the space at the bottom of the test tube on the inner wall of the storage box 1 in real time and transmit it to the external controller 4 through internal circuits and other means. The fan 18 will pour fresh air into the storage box 1 from the bottom of the inner wall. The incoming air will pass through the inclined surface of the conical electric heating block 19 and pass through the annular ventilation window 21 on the outer wall of the air guide seat 12, and then pour the air into the porous rubber pad 10, so as to cool the sample stored inside the sample test tube. When the temperature sensor 11 detects that the temperature inside the storage box 1 is too low, it will transmit a signal to the controller 4 to start the heating motor 20, so as to heat the surface of the conical electric heating block 19. Then, the air blown by the fan 18 will bring the surface heat to the inside of the porous rubber pad 10 when it touches the conical heating block 19, so as to heat the inside of the storage box 1, thus reasonably adjusting the temperature of the sample storage test tube stored inside the storage box 1 and improving the sample storage quality of the sample storage test tube.
