[0015] Compared with the prior art, the utility model provides a sample storage device for coalbed methane exploration, which has the following beneficial effects:

[0016] The sample storage device for coalbed methane exploration has a sealing door installed on the surface of the storage tank, through which the storage tank can be opened and closed, and the size of the opening is slightly larger than the test tube for preventing the sample, so the storage device does not need to be opened as a whole from the top when the device is in use, thereby preventing debris from entering the storage device, and at the same time, because a rotating shaft is installed inside the tank body, a driven wheel is installed outside the rotating shaft, and a belt is installed between the driven wheel and the driving wheel, so when the motor drives the shaft rod and the driving wheel to rotate, the rotating shaft can drive the placement mechanism to rotate Since the placement mechanism is composed of multiple groups of placement seats, an upper fixed plate and a lower fixed plate, the placement seat with the sample placed thereon can be moved to the position of the sealing door, thereby facilitating the taking, placing and searching of the sample. At the same time, since a groove is installed on the surface of the placement seat, and a reset spring and a connecting block are sleeved on the surface of the slide bar in the groove, the reaction force of the reset spring enables the connecting block to push the clamping seat to move toward the middle of the placement seat through the connecting seat, thereby cooperating with the placement groove of the placement seat to clamp and fix the sample test tube. Therefore, the device can ensure the storage stability of the sample when it is in use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , Figure 4 and Figure 5 In this embodiment: a sample storage device for coalbed methane exploration includes a base 1, a storage tank 2 is arranged above the base 1, a sealing door 3 is arranged on the front of the storage tank 2, the storage tank 2 is sealed by the sealing door 3, and a rotating shaft 5 is arranged inside the storage tank 2;

[0025] A transmission mechanism 4 is provided on one side of the storage tank 2, a placement mechanism 6 is provided on one side of the rotating shaft 5, a fixing mechanism 7 is provided on one side of the placement mechanism 6, and a groove 8 is provided on one side of the placement mechanism 6;

[0026] The placement mechanism 6 includes an upper fixed plate 61, a lower fixed plate 62, a placement seat 63 and a placement slot 64. The upper fixed plate 61 is fixedly installed above the placement seat 63, the lower fixed plate 62 is fixedly installed below the placement seat 63, and the placement slot 64 is opened inside the placement seat 63. The placement mechanism 6 is used to place sample test tubes.

[0027] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the transmission mechanism 4 includes a motor 41, a shaft 42, a driving wheel 43, a belt 44 and a driven wheel 45. The motor 41 is connected to the shaft 42 at the bottom, the driving wheel 43 is fixedly installed on the outside of the shaft 42, the belt 44 is sleeved on the outside of the driving wheel 43, and the driven wheel 45 is sleeved on the inside of the belt 44.

[0028] In the above embodiment, the shaft 42 can be driven to rotate by the motor 41 of the transmission mechanism 4. Since a driving wheel 43 is installed under the shaft 42, the driving wheel 43 rotates synchronously, and the transmission belt 44 sleeved between the driving wheel 43 and the driven wheel 45 can rotate the driven wheel 45.

[0029] Furthermore, the driven wheel 45 is fixedly mounted on the outer surface of the rotating shaft 5 , the belt 44 is sleeved between the driving wheel 43 and the driven wheel 45 , and the motor 41 is fixedly mounted on one side of the upper surface of the storage tank 2 .

[0030] Since the driven wheel 45 is installed on the outer surface of the rotating shaft 5, the rotating shaft 5 can be rotated when the driving wheel 43 drives the driven wheel 45 to rotate through the belt 44. At the same time, the diameter of the driving wheel 43 is smaller than that of the driven wheel 45, so the driving wheel 43 rotates one circle and the driven wheel 45 rotates one third of a circle to achieve slow rotation of the rotating shaft 5.

[0031] See also Figure 2 , Figure 4 and Figure 5 In this embodiment, the fixing mechanism 7 includes a slide rod 71, a return spring 72, a connecting block 73, a connecting seat 74 and a clamping seat 75. The outer portion of the slide rod 71 is sleeved with the return spring 72, the connecting block 73 is fixedly connected to the connecting seat 74, and the clamping seat 75 is fixedly installed above the connecting seat 74.

[0032] In the above embodiment, the reset spring 72 can be restricted inside the groove 8 by the slide rod 71, and the connecting block 73 is installed with the clamping seat 75 through the connecting seat 74, so that under the action of the reset spring 72, the connecting block 73 can drive the clamping seat 75 to move through the connecting seat 74.

[0033] Among them, the sliding rod 71 is fixedly installed inside the groove 8, the connecting block 73 is fixedly connected to the return spring 72, the connecting block 73 is sleeved on the surface of the sliding rod 71, and the clamping seat 75 is provided with two groups, and the clamping seat 75 is mirror-arranged on the surface of the placement mechanism 6.

[0034] The two sets of clamping seats 75 can cooperate with the lower placement mechanism 6 to clamp and fix the upper surface and the lower surface of the test tube storing the sample, thereby ensuring the stability of the storage device for sample placement.

[0035] See also Figure 2 and Figure 4 It is worth noting that the upper fixed plate 61 and the lower fixed plate 62 are fixedly mounted on the rotating shaft 5, the placement seat 63 is arranged around the upper fixed plate 61 and the lower fixed plate 62, the placement groove 64 is an arc groove, and the groove 8 is located at the four corners of one side surface of the placement seat 63.

[0036] By installing the upper fixed plate 61 and the lower fixed plate 62 with the rotating shaft 5, the rotating shaft 5 can drive the two to rotate, so that the placement seat 63 located between the two can rotate in a circle, and the placement groove 64 is an arc groove, so that the placement seat 63 can prevent cylindrical sample tubes.

[0037] In addition, the storage tank 2 is fixedly installed on the base 1, the sealing door 3 is movably connected to the storage tank 2, and the rotating shaft 5 is movably connected to the middle part of the storage tank 2. The storage tank 2 can be opened through the sealing door 3 to take out the test tube storing the sample inside.

[0038] The working principle and use process of the utility model are as follows: after the operator opens the sealing door 3, the operator pushes the clamping seat 75 upward and downward at the same time so that the connecting seat 74 compresses the reset spring 72 through the connecting block 73, and after the test tube with the sample placed is sent into the inside of the placement groove 64, the clamping seat 75 is loosened. Due to the reaction force of the reset spring 72, the connecting block 73 pushes the clamping seat 75 to move through the connecting seat 74 to clamp and fix the test tube in the placement seat 63, and then the shaft 42 is driven to rotate by starting the motor 41, so that the driving wheel 43 drives the driven wheel 45 to rotate through the belt 44, and then the rotating shaft 5 drives the placement mechanism 6 to rotate slowly, and another set of free placement seats 63 is rotated to the sealing door 3. Through the same operation, the test tubes are placed in the inside of the placement seat 63 in turn, and the sealing door 3 can be closed to store the samples. When the sample needs to be taken out, it is only necessary to open the sealing door 3, start the motor 41, and rotate the placement seat 63 to the position of the sealing door 3, and the test tube containing the sample in the placement seat 63 can be taken out by pushing the clamping seat 75.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
