Abstract
Description
Technical Field
[0001] This utility model relates to the field of static leveling technology, and in particular to a static leveling sealing mechanism and deoxygenation device suitable for damp corridors. Background Technology
[0002] Existing hydrostatic leveling protection boxes have significant shortcomings in terms of airtightness. Their enclosures are made of stainless steel, a material highly sensitive to temperature changes. Under the prolonged exposure to the humid environment inside the corridor, the core component of the hydrostatic level—the movement—is highly susceptible to corrosion, significantly shortening its lifespan. Furthermore, the marker poles inside the protection box are also vulnerable; the humid environment becomes a breeding ground for microorganisms. The proliferation of these microorganisms not only contaminates the marker poles but also significantly interferes with the accuracy of their displacement changes. When the humidity in the corridor increases further, the CCD sensor installed inside the protection box also faces severe challenges. Its signal display becomes blurred due to moisture condensation, and the reception of light signals is severely hampered, leading to a significant reduction in the accuracy and real-time performance of data acquisition. Even more seriously, the stainless steel material on the top of the protection box will gradually corrode and even become damaged under long-term humid conditions, further weakening the overall protective performance of the protection box and posing a potential threat to the stable operation of the hydrostatic leveling system.

[0010] As a preferred embodiment of the static leveling sealing mechanism for damp corridors described in this utility model, the bottom end of the groove is provided with a slot, and the bottom end of the sealing box is provided with a locking post; the locking post is adapted to the slot.

[0012] As a preferred embodiment of the static leveling sealing mechanism for damp corridors described in this utility model, the sealing box is provided with a drying box, and a drying component is placed inside the drying box; the drying component is used to absorb moisture inside the sealing box.
[0013] As a preferred embodiment of the static leveling sealing mechanism for damp corridors described in this utility model, a sealing strip is provided around the perimeter of the box door, and a water-blocking eaves are provided at the top of the sealing box.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1
[0028] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a static horizontal sealing mechanism suitable for damp corridors, including a sealing box 1, the bottom end of which is open.
[0029] The blocking block 2 includes a first blocking wall 21 and a second blocking wall 22, and a groove 23 is formed between the first blocking wall 21 and the second blocking wall 22. The groove 23 is adapted to the bottom end of the sealing box 1.
[0030] The groove 23 is filled with a separating fluid;
[0031] When the bottom of the sealed box 1 is inserted into the groove 23 and comes into contact with the isolation liquid, the inner wall of the sealed box 1 forms a sealed space. The sealed space can isolate the humid environment of the outer wall of the sealed box 1. By placing the bottom of the sealed box 1 in the groove 23, the air on the outer wall of the sealed box 1 cannot enter the inner wall of the sealed box 1 through the isolation liquid in the groove 23, thereby isolating the air on the outer wall of the sealed box 1. At the same time, the sealed box 1 prevents the humid isolation liquid on its outer wall from entering the interior of the sealed box 1.
[0032] It should be noted that the inner wall of the sealed box 1 forms a receiving space, which is used to accommodate the static leveling instrument. Since the static leveling instrument needs to be in direct contact with the ground, the bottom of the sealed box 1 needs to be open.
[0033] In the existing technology, when a static leveling instrument needs to be used in a damp corridor, the existing sealed box 1 has poor sealing performance and is made of stainless steel which is greatly affected by temperature changes. It is easily affected by the humid environment in the corridor, which causes the static leveling mechanism to rust and affect its lifespan. Microorganisms grow on the marker pole, affecting displacement changes. When the humidity in the corridor is too high, the CCD sensor signal screen becomes blurry, the light sensor signal reception is blocked, and the top of the protective box rusts and is damaged.
[0034] To solve the above problems, our technical solution is to set up a first barrier wall 21 and a second barrier wall 22 around the ground to be tested to form a barrier block 2. A groove 23 is formed between the first barrier wall 21 and the second barrier wall 22. The gap between the first barrier wall 21 and the second barrier wall 22 and the ground is sealed with cement or colloid. Then, the groove 23 is filled with isolation liquid. Subsequently, the bottom end of the sealing box 1 is inserted into the groove 23. Since the groove 23 is filled with isolation liquid, the gas on the outer wall of the sealing box 1 cannot enter the inner wall of the sealing box 1 through the isolation liquid in the groove 23.
[0035] At this time, the connection between the sealing box 1 and the groove 23 is sealed. At the same time, the sealing box 1 isolates the external humid environment, ensuring that the static level instrument will not rust due to the humid environment of the corridor, and ensuring that the components inside the sealing box 1 will not be affected by the humid environment.
[0036] Example 2
[0037] Reference Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, the first blocking wall 21 is provided with a first through hole, and the second blocking wall 22 is provided with a second through hole. The first through hole and the second through hole are located on the same horizontal line.
[0038] Specifically, a first pipe 3 is provided on the side of the first through hole away from the groove 23, and a second pipe 4 is provided on the side of the second through hole away from the groove 23.
[0039] It should be noted that the highest point of the first pipe 3 and the second pipe 4 is higher than the top of the first barrier wall 21 and the second barrier wall 22. This arrangement can prevent the isolation liquid from flowing out of the first pipe 3 and the second pipe 4. The first pipe 3 and the second pipe 4 are used to pass the cables in the sealing box 1 through the isolation liquid and out of the barrier block 2. This arrangement can prevent the sealing performance of the sealing box 1 from being compromised by creating holes in the sealing box 1.
[0040] Furthermore, a third through hole is provided on the bottom side wall of the sealing box 1; when the bottom of the sealing box 1 is inserted into the groove 23, the first through hole, the second through hole and the third through hole are connected.
[0041] refer to Figure 4 and Figure 5It should be noted that the third through hole is used to pass the cable inside the sealed box 1. When the cable inside the sealed box 1 passes through the second pipe 4, the second through hole, the groove 23 with the isolation liquid, and the first through hole and exits through the first pipe 3, the third through hole on the side wall of the sealed box 1 will not allow air to enter the outer wall of the sealed box 1.
[0042] Furthermore, a slot 5 is provided at the bottom of the groove 23, and a locking post 6 is provided at the bottom of the sealing box 1; the locking post 6 is compatible with the slot 5.
[0043] It should be noted that when the sealing box 1 is inserted into the groove 23, the sealing box 1 and the groove 23 are connected by the locking post 6 and the locking slot 5.
[0044] Furthermore, a drying box 72 is provided inside the sealed box 1, and a drying element is placed inside the drying box 72; the drying element is used to absorb moisture inside the sealed box 1. It should be noted that the drying element can be a desiccant.
[0045] Furthermore, a sealing strip is provided around the perimeter of the door 7, and a water-blocking eaves 11 is provided at the top of the sealed box 1. The water-blocking eaves 11 are used to protect the top of the sealed box 1 from corrosion by dripping water from the arch of the corridor.
[0046] The rest of the structure is the same as in Example 1.
[0047] Example 3
[0048] Reference Figures 1-3 This is the third embodiment of the present invention. Unlike the previous embodiments, this embodiment provides a static horizontal deoxygenation device suitable for damp corridors. It includes the above-mentioned static horizontal sealing mechanism suitable for damp corridors, and also includes a vent pipe 8. One end of the vent pipe 8 is connected to the deoxygenation chamber 9, and the other end of the vent pipe 8 is connected to the side wall of the sealing box 1. The deoxygenation chamber 9 is provided with a deoxygenation component. The deoxygenation component is used to consume the oxygen in the sealing box 1.
[0049] Furthermore, a stop valve is installed inside the vent pipe 8, which is used to control the airflow status between the deaerator chamber 9 and the sealed box 1.
[0050] It should be noted that when the sealed box 1 is inserted into the groove 23 and the box door 7 is closed, the humid air on the outer wall of the sealed box 1 will not enter the inner wall of the sealed box 1 because the box door 7 is equipped with a sealing strip and the groove 23 is equipped with a sealing liquid. However, there is still oxygen inside the sealed box 1. In order to reduce the impact of the oxygen inside the sealed box 1 on the hydrostatic level instrument, we can consume the oxygen inside the sealed box 1 through an oxygen scavenger. In this embodiment, the combustion oxygen consumption method is taken as an example. The specific operation process is as follows:
[0051] First, close the stop valve, then open the door of the deoxygenation chamber 9, light the alcohol lamp, then close the door of the deoxygenation chamber 9 again, and open the stop valve so that the gas in the sealed box 1 can enter the deoxygenation chamber 9 through the vent pipe 8. When the gas in the deoxygenation chamber 9 and the sealed box 1 is completely consumed, the alcohol lamp will automatically go out, thereby achieving the purpose of deoxygenating the sealed box 1.
[0052] The rest of the structure is the same as in Example 2.
