Description

Technical Field

[0001] The utility model relates to the technical field of water sample storage, in particular to a hydrological and water resource water sample storage device. Background Art

[0002] Hydrology refers to the various changes in the forms, circulation, distribution and properties of water in nature. It also refers to the various phenomena of water changes and movements in nature. Surveying the hydrology and water resources at the target location can detect the hydrological information and geological properties of the current landform. After sampling the water sample, a storage device is required for loading.

[0003] According to a hydrogeological water sample storage device disclosed in Chinese patent publication No. CN216187251U, the patent can protect the water sample tube by arranging a cover plate, a buffer device, a second rubber pad and a third rubber pad. The placement rack can be easily pulled out through the sliding connection between the support frame and the placement rack. The water sample tube can be clamped through the cooperation between the third spring and the first rubber pad. However, the patent still has certain inconveniences in actual use. Since the third spring clamps the water sample tube through the first rubber pad, and the first rubber pad has a large friction force, when the water sample tube needs to be pulled out, it is necessary not only to overcome the elastic force of the third spring but also to overcome the friction force of the first rubber pad, which makes it difficult to easily pull out the water sample tube, and the actual operation is not convenient. In this regard, the present application provides a hydrological and water resources water sample storage device to solve the above problems. Utility Model Content

[0027] 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.

[0028] See also Figure 1-4 The utility model provides a technical solution: a hydrological and water resource water sample storage device, comprising an outer box 1, a box cover assembly 200 for protecting the sample is installed on the outer side of the outer box 1, and a storage mechanism for placing the sample is installed on the inner side of the outer box 1; through the coordinated use of the box cover assembly 200 on the outer side of the outer box 1 and the sliding assembly 300 and the storage assembly 500 on the inner side, the water sample can be limited and protected while being convenient to take out, so that when the water sample needs to be taken out for testing, it can be done easily, and at the same time, the sliding and pulling-out method of the water sample placement rack is optimized, so that it can be pulled out more easily, which greatly improves the convenience in the actual operation process, thereby effectively improving the practicality of the water sample storage device.

[0029] It should be noted that the storage mechanism includes a sliding component 300 installed on the inner bottom wall of the outer box 1 for extracting the corresponding multiple groups of samples and a storage component 500 installed on the top of the sliding component 300 for storing and protecting the samples. By using the sliding component 300 in conjunction with the storage component 500, it is convenient to take out the samples and also conveniently take out the same group of samples at one time.

[0030] In this embodiment, the storage component 500 is a structure for storing samples and capable of elastically positioning the samples.

[0031] like Figure 1 and Figure 2As shown, the storage assembly 500 includes three groups of inner cylinders 501, the inner side of the inner cylinder 501 is slidably connected with a placement cylinder 502, the top and bottom of the inner side of the placement cylinder 502 are bonded with high-elastic sponges 503, the inner side of the placement cylinder 502 is provided with four mounting grooves 504 located in the same horizontal plane, the inner side of the mounting groove 504 is fixedly connected with two positioning rods 505, the inner side of the mounting groove 504 is fixedly connected with two first springs 506, the outer sides of the corresponding two positioning rods 505 are slidably connected with a mounting plate 507, the end of the positioning rod 505 is fixedly connected with a limiting disk 508, a roller assembly is fixedly installed on the side of the mounting plate 507 away from the corresponding placement cylinder 502, and a buffer assembly is installed on the inner side of the inner cylinder 501.

[0032] It should be noted that the number of inner cylinders 501 in each group is not less than two, and can be changed according to the actual size of the outer box 1. Specifically, the number of inner cylinders 501 in each group is three, and the same group of experimental samples or matching samples that need to be subjected to a control experiment can be placed on the inner side of the cylinder 502 placed inside the same group of inner cylinders 501.

[0033] In addition, the first spring 506 is located on the outer side of the corresponding positioning rod 505, and the side of the first spring 506 close to the corresponding mounting plate 507 is fixedly connected to the outer side of the mounting plate 507, so that the mounting plate 507 can drive the corresponding two first springs 506 to stably undergo elastic deformation when moving. The diameter of the limiting plate 508 is larger than the diameter of the positioning rod 505. The limiting plate 508 is located on the side of the mounting plate 507 away from the corresponding placement tube 502, so that the limiting plate 508 can play a role of limiting and blocking the mounting plate 507.

[0034] In this embodiment, the roller assembly is a structure used to facilitate the up and down movement of the sample test tube.

[0035] like Figure 2 As shown, the roller assembly includes two connecting plates 509 fixedly connected to the corresponding mounting plate 507 away from the corresponding placement cylinder 502, and a round rod 510 is rotatably connected between the opposite sides of the two connecting plates 509 through a bearing, and a positioning roller 511 is fixedly connected to the outer side of the round rod 510.

[0036] It should be noted that the corresponding four positioning rollers 511 are located on the same horizontal plane, which can facilitate the elastic positioning of the sample test tube. The diameters at both ends of the positioning roller 511 are equal and both are larger than the diameter at the center. A rubber pad is bonded to the outer side of the positioning roller 511. The corresponding four positioning rollers 511 can play a good limiting role for the sample test tube.

[0037] In this embodiment, the buffer assembly is a structure used to provide buffering and vibration reduction protection for the bottom of the placement tube 502 .

[0038] like Figure 1As shown, the buffer assembly includes a transition block 512 fixedly connected to the bottom of the placement cylinder 502, a second spring 513 is fixedly connected between the bottom of the transition block 512 and the inner bottom wall of the corresponding inner cylinder 501, a small damper 514 is fixedly connected between the bottom of the transition block 512 and the inner bottom wall of the corresponding inner cylinder 501, and a limiting frame 515 is fixedly connected to the inner side of the inner cylinder 501.

[0039] It should be noted that the small damper 514 is located on the inner side of the corresponding second spring 513, so that the small damper 514 can cooperate with the corresponding second spring 513 to perform the function of buffering and vibration reduction. The limit frame 515 is located on the top of the corresponding transition block 512, and the inner diameter of the limit frame 515 is smaller than the diameter of the transition block 512, so that the limit frame 515 can limit the transition block 512.

[0040] In this embodiment, the box cover assembly 200 is used to protect the internal structure of the outer box 1 and the structure of the sample.

[0041] like Figure 1 and Figure 4 As shown, the box cover assembly 200 includes a switch cover 201 hinged to the top of the outer box 1, a fixing plate 202 is fixedly connected to the inner side of the switch cover 201, a rubber plate 203 is bonded to the bottom of the fixing plate 202, a PE foam 204 is bonded to the bottom of the rubber plate 203, a front cover 205 is hinged to the front of the outer box 1, and handles 4 are penetrated and fixedly installed on both the left and right sides of the outer box 1.

[0042] It should be noted that the top and the front of the outer box 1 are both opened, so that the sample can be normally removed through the top and the front of the outer box 1. Two buckles are fixedly installed between the front of the switch cover 201 and the front of the outer box 1. The two buckles are respectively located on the left and right sides of the front cover 205. The switch cover 201 can be locked or opened by the buckles. Lock buckles are fixedly installed between the left and right sides of the front cover 205 and the front of the outer box 1 respectively. The front cover 205 can be locked or opened by the lock buckles.

[0043] In addition, the bottom of the PE foam 204 is provided with evenly distributed arc grooves, the positions and number of the arc grooves correspond to the positions and number of the placement tube 502, respectively, and the top end of the sample test tube inside the placement tube 502 can be placed through the arc grooves. When the sample test tube is located on the inner side of the arc groove, the PE foam 204 of this part will be pushed to deform, thereby protecting the top end and the outer side of the top end of the sample test tube under the wrapping effect of the PE foam 204 and the elastic support effect of the rubber plate 203.

[0044] In this embodiment, the sliding assembly 300 is a structure for conveniently and easily extracting samples of the same group.

[0045] like Figure 1 and Figure 3 As shown, the sliding assembly 300 includes three partition plates 301 fixedly connected to the inner bottom wall of the outer box 1, three sliding plates 302 are slidably connected to the inner side of the outer box 1, six evenly distributed slide rails 303 are fixedly installed on the inner bottom wall of the outer box 1, six limit blocks 304 are fixedly connected to the inner bottom wall of the outer box 1, two limit grooves 305 for sliding of two corresponding limit blocks 304 are provided at the bottom of the sliding plate 302, three threaded cylinders 306 with open tops are fixedly connected to the inner bottom wall of the outer box 1, and a hand screw 307 is passed through the top of the sliding plate 302.

[0046] It should be noted that the three groups of inner cylinders 501 are connected to the three sliding plates 302 respectively by screws, so that the inner cylinders 501 can be removed from the top of the sliding plates 302. The limit blocks 304 are trapezoidal, and the front and back sides of the limit grooves 305 are both open. Through the coordinated use of the limit blocks 304 and the limit grooves 305, the sliding plates 302 can slide stably on the top of the corresponding two slide rails 303.

[0047] In addition, the slide rail 303 includes a sliding groove box fixedly connected to the inner bottom wall of the outer box 1, the top of the sliding groove box is open, the inner side of the sliding groove box is rotatably connected to a uniformly distributed rotating rod through a bearing, the outer side of the rotating rod is fixedly connected to a round roller, the top of the round roller fits with the bottom of the corresponding sliding plate 302, and the sliding plate 302 can be moved smoothly by rotating the round roller, and the hand screw 307 is threadedly connected to the inner side of the corresponding threaded tube 306, so that the hand screw 307 can pass through the top of the corresponding sliding plate 302 and be threadedly connected to the inner side of the corresponding threaded tube 306, thereby realizing the function of threaded connection positioning, so that the sliding plate 302 is not easy to move after being positioned by the hand screw 307.

[0048] The working principle of the above embodiment is:

[0049] (1) When it is necessary to store water samples, open the switch cover 201 and insert the sample tube into the inner side of the placement tube 502. Under the action of the high elastic sponge 503 inside, the outer side of the sample tube can be protected. At the same time, the insertion of the sample tube will cause the corresponding four positioning rollers 511 to move to the side away from the sample tube, thereby driving the mounting plate 507 to move on the inner side of the corresponding mounting groove 504, so that the first spring 506 is compressed. Under the elastic recovery action of the first spring 506, pressure is applied to the outer side of the sample tube through the positioning roller 511, thereby playing a role of elastic positioning. Sample tubes of the same group or those to be subjected to comparative tests can be placed on the inner side of the placement tube 502 at the top of the same sliding plate 302, which is convenient for subsequent water sample detection. Close the switch cover 201, so that the PE foam 204 moves to the top of the sample tube. Under the elastic protection action of the PE foam 204, the top and the outer side of the top of the sample tube can be elastically protected. The outer box 1 can be moved by the handle 4.

[0050] (2) When testing is required, the switch cover 201 is opened and the sample tube can be directly pulled out upwards. Under the rotation of the positioning roller 511, the sample tube can be easily detached from the inner side of the placement tube 502, which is convenient for water sample testing. When it is necessary to select the sample tube placed on the top of the same sliding plate 302, the front cover 205 is opened and the hand-screw 307 is loosened, and the sliding plate 302 can be pulled toward the front side so that it can move under the sliding support of the two corresponding slide rails 303. Under the cooperation between the limit block 304 and the corresponding limit groove 305, the sliding plate 302 can be limited, so that the sliding plate 302 can slide stably, and the sliding plate 302 can be pulled out from the inner side of the outer box 1, which is convenient for the staff to compare and test the same group of samples.

[0051] Compared with the prior art, the hydrological and water resource water sample storage device, through the coordinated use of the box cover assembly 200 on the outside of the outer box 1 and the sliding assembly 300 and the storage assembly 500 on the inside, can limit the protection of the water sample while facilitating its removal, so that the water sample can be easily removed for testing when it is needed. At the same time, the sliding withdrawal method of the water sample placement rack is optimized, so that it can be pulled out more easily, which greatly improves the convenience in the actual operation process, thereby effectively improving the practicability of the water sample storage device and solving the problem that it is inconvenient to remove water samples in the existing water sample storage device.

[0053] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
