[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Secondly, the "one embodiment" or "embodiment" referred to herein refers to a specific feature, structure or characteristic that can be included in at least one implementation of the utility model. The "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figure 1 and 2 , which is the first embodiment of the utility model, and this embodiment provides a monitoring mechanism.

[0036] The monitoring mechanism includes a monitoring component 100 .

[0037] Specifically, the monitoring component 100 includes a placement plate 101. The placement plate 101 is arranged to facilitate the placement of alcohol bottles. The placement plate 101 is provided with through holes 101a in an array, and the through holes 101a penetrate the placement plate 101. Through the arrangement of the through holes 101a, when alcohol leaks, it can flow into the monitoring box 102 at the bottom of the placement plate 101 through the through holes 101a. The monitoring box 102 is located at the bottom of the placement plate 101. One side of the monitoring box 102 is hinged with a sealing plate 103. The monitoring box 102 and the sealing plate 103 are made of uniform transparent materials, so that it is convenient for the staff to check the shape change of the bentonite 104 inside the monitoring box 102. When alcohol leaks, it can be checked and handled in time, thereby reducing the occurrence of accidents caused by alcohol leakage.

[0038] It is worth noting that bentonite 104 is paved inside the monitoring box 102 (the bentonite 104 is an adsorbent made by inorganic acidification, water rinsing and drying. It has the appearance of a milky white powder, is odorless, tasteless, non-toxic, and has strong adsorption properties. It belongs to the prior art and will not be described in detail here). Through the setting of bentonite 104, when alcohol leaks and drips onto the bentonite 104, the bentonite 104 expands 10 times after absorption, and there is an obvious shape change to warn the staff, making it easier for the staff to check and thus promptly discover the leakage of alcohol.

[0039] Preferably, a moving part 105 is provided on the back of the monitoring box 102. Through the setting of the moving part 105, when the bentonite 104 swells upon contact with alcohol to warn of alcohol leakage, the swollen alcohol is cleaned up, so that the new dry bentonite 104 can be laid, thereby ensuring the monitoring effect of alcohol in the later stage.

[0040] Furthermore, the inner wall of the monitoring box 102 is provided with a replenishment piece 106. Through the provision of the replenishment piece 106, the bentonite 104 can be replenished in time after being cleaned after use, thereby ensuring the monitoring effect of alcohol leakage.

[0041] When in use, the staff is first required to transport the medical alcohol bottles to be used to the shelves in the storage room. When the cracked alcohol bottles due to improper transportation begin to leak alcohol, they slide into the monitoring box 102 through the through hole 101a, and come into contact with the bentonite 104 laid in the monitoring box 102. The bentonite 104 expands to dozens of times after absorbing the leaked alcohol. At the same time, due to the transparent material setting of the monitoring box 102 and the sealing plate 103, the staff can timely check the changes of the bentonite 104 inside the monitoring box 102, thereby checking the alcohol bottles on the relevant placement plate 101 and handling the damaged alcohol bottles, thereby avoiding the aggravation of alcohol leakage accidents.

[0042] Example 2

[0043] Reference Figure 1-3 , which is the second embodiment of the present utility model, is based on the previous embodiment, and is different from the previous embodiment in that: this embodiment provides an alcohol storage device.

[0044] The monitoring assembly 100 also includes a moving part.

[0045] Specifically, a storage groove 105a is provided on one side of the monitoring box 102. The storage groove 105a is provided to facilitate the storage of the scraper 105d. A screw rod 105b is threadedly connected to the monitoring box 102. The setting of the screw rod 105b facilitates the scraper 105d to slide back and forth when the screw rod 105b rotates. A turning handle 105c is welded to one end of the screw rod 105b. The setting of the turning handle 105c facilitates the staff to rotate the screw rod 105b, which makes the operation more convenient. A scraper 105d is threadedly connected to the screw rod 105b. The setting of the scraper 105d can timely clean the expanded bentonite 104, which makes the operation more convenient.

[0046] Preferably, the inner wall of the monitoring box 102 is provided with a first slide rail 106a, and a first slider 106f is slidably installed inside the first slide rail 106a. The setting of the first slide rail 106a facilitates the sliding of the first slider 106f, and the first slide rail 106a is inclined so that the first slider 106f continuously moves upward during the movement. The inner wall of the monitoring box 102 is provided with a limiting groove 106b, and the limiting groove 106b is located at the bottom of the first slide rail 106a. The setting of the limiting groove 106b facilitates the adjustment plate 106c to adjust the position by translation. The limiting groove 106b is slidably installed with an adjustment plate 106c. The setting of the adjustment plate 106c facilitates the opening of the gap on one side of the monitoring box 102, so that the dry bentonite 104 can enter smoothly. In the monitoring box 102, replenishment is completed, and a first spring 106d is arranged on the outer side of the adjustment plate 106c. Through the setting of the first spring 106d, when it is affected by external force, elastic deformation occurs, driving the adjustment plate 106c on one side to move backward, opening the gap for replenishment. When it is not affected by external force, the first spring 106d restores the elastic force, driving the adjustment plate 106c to move forward, thereby closing the gap, blocking the replenishment, and avoiding waste caused by excessive replenishment. A telescopic rod 106e is arranged on the top of the adjustment plate 106c, and a first slider 106f is arranged on the top of the telescopic rod 106e. Through the setting of the telescopic rod 106e, the adjustment plate 106c is connected to the first slider 106f, and can be extended with the height of the first slider 106f, which is more practical.

[0047] Furthermore, an adjusting block 106g is slidably installed inside the first slider 106f, and one end of the adjusting block 106g is set to a triangle. Through the setting of the triangle of the adjusting block 106g, when the scraper 105d moves forward, it slides toward the inside of the first slider 106f. When the scraper 105d moves backward, it pushes the adjusting block 106g to move in the same direction, thereby driving the adjusting plate 106c to move in the same direction to complete the displacement and realize the replenishment action of the bentonite 104. The other end of the adjusting block 106g is provided with a second spring 106h. Through the setting of the second spring 106h, when the scraper 105d moves forward and does not contact the adjusting block 106g, the second spring 106h is no longer compressed by the external force to restore the elastic force, and the adjusting block 106g is popped out from the first slider 106f, so that the adjusting block 106g contacts the scraper 105d when the scraper 105d moves backward to achieve the displacement effect.

[0048] When in use, the staff first rotates the handle 105c clockwise, and the screw rod 105b rotates coaxially under the drive of the handle 105c, thereby driving the scraper 105d on the screw rod 105b to move forward, completing the cleaning of the bentonite 104 on the monitoring box 102, and then rotates the handle 105c counterclockwise, and the screw rod 105b rotates coaxially under the drive of the handle 105c, thereby driving the scraper 105d on the screw rod 105b to move backward, contacting the adjustment block 106g on the first slider 106f, pushing the adjustment block 106g and the first slider 106f to move in the same direction, and under the action of the first slide rail 106a, the first slider 106f and the adjustment block 106g While moving backward, it moves diagonally upward, thereby realizing that the adjusting plate 106c at the bottom of the first slider 106f moves in the same direction, opening the gap of the monitoring box 102, so that the supplementary material of bentonite 104 can smoothly enter the monitoring box 102, and when the first slider 106f and the adjusting block 106g slide to the moving height, the bottom and the top of the scraper 105d are at the same horizontal height, and the scraper 105d continues to move backward, The contact between the scraper 105d and the adjusting block 106g is released, and then the first spring 106d on the side of the adjusting plate 106c restores the elastic force, driving the adjusting plate 106c to move forward, thereby realizing the closing of the gap, blocking the replenishment, and avoiding waste caused by excessive replenishment.

[0049] Example 3

[0050] Reference Figure 4-6 , which is the third embodiment of the present utility model, is based on the previous embodiment, and is different from the previous embodiment in that: this embodiment provides an alcohol storage device.

[0051] The alcohol storage device includes a cleaning assembly 200 .

[0052] Specifically, the cleaning component 200 includes a rack 201. The rack 201 is provided to facilitate the installation of the monitoring component 100. The rack 201 is provided outside the monitoring component 100. A flow slot 202 is longitudinally provided on the rack 201. A fixing frame 207 is longitudinally welded on the rack 201. The fixing frame 207 is provided to facilitate fixing a storage box 208 on one side of the rack 201. A storage box 208 is provided on the top of the fixing frame 207. The storage box 208 is provided to facilitate multiple batches of bentonite 104 preparations at one time, which facilitates the replenishment of the bentonite 104 after use, and is more convenient to operate. The storage box 208 is provided with a flow slot 202 of the same type. The flow slot 202 is provided to facilitate the bentonite 104 preparations in the storage box 208 to smoothly enter the monitoring box 102. In the embodiment, a pushing member 203 is longitudinally arranged on the storage rack 201. Through the setting of the pushing member 203, the bentonite 104 cleaned out of the monitoring box 102 can be quickly processed, which saves the operating steps of the staff, and the operation is faster, more convenient, and has a higher safety factor. A limiting seat 205 is welded on one side of the storage rack 201. Through the setting of the limiting seat 205, it is convenient to place the smoothing plate 206 and avoid the loss of the smoothing plate 206. The limiting seat 205 is movably sleeved with a smoothing plate 206. Through the setting of the smoothing plate 206, when the monitoring box 102 is supplemented with materials, the bentonite 104 can be promptly flattened through the smoothing plate 206, ensuring that the internal bottom plate of the monitoring box 102 is evenly paved with bentonite 104, ensuring that when alcohol leaks, it can drip to any part of the monitoring box 102. Changes can occur, which is convenient for staff to check.

[0053] Preferably, a storage frame 203a is welded longitudinally on the storage rack 201. Through the setting of the storage frame 203a, the used bentonite 104 cleaned by the scraper 105d can be collected in time. A second slide rail 203b is provided on the outside of the storage frame 203a, and a second slider 203c is slidably installed inside the second slide rail 203b. A cleaning plate 203d is provided on one side of the second slider 203c. The opening of the second slider 203c facilitates the movement of the second slider 203c, thereby driving the cleaning plate 203d to move from one end of the storage frame 203a to the other end, thereby realizing the processing operation of the bentonite 104 in the storage frame 203a. A push rod 203e is provided on the other side of the second slider 203c. Through the setting of the push rod 203e, the staff can better operate the second slider 203c to slide on the second slide rail 203b.

[0054] Furthermore, a conveying pipe 204 is provided on one side of the storage frame 203a, and the conveying pipe 204 is provided on one side of the rack 201. Through the setting of the conveying pipe 204, it is convenient to convey the bentonite 104 cleaned up from a high place to the bottom, so that the staff can collect and centrally process it in garbage bags. A blocking plate 204a is hingedly provided on the conveying pipe 204. Through the setting of the blocking plate 204a, when the bentonite 104 on one side of the rack 201 is processed, it can be prevented that the bentonite 104 moves downward in the conveying pipe 204 and drifts to other storage frames 203a.
