Description

Technical Field

[0001] This utility model relates to the field of spraying equipment, and in particular to a container assembly, a spraying mechanism, and a trolley for treating hazardous gases in tunnels. Background Technology

[0002] Underground tunnels are an indispensable and important part of the construction of pumped storage power stations. During the construction of underground tunnels, harmful gases such as CO and H2S will be generated due to the different rock media. If these harmful gases are not treated in time, they will cause harm to the human body and may even lead to suffocation and death. The treatment of CO and H2S is generally carried out by spraying hopalat powder particles and sodium carbonate solution.

[0003] Existing spraying equipment is entirely exposed. Since the spraying materials for CO and H2S control are powder particles and sodium carbonate solution, the powder easily adheres to the equipment surface, affecting its use. Furthermore, the sodium carbonate solution is corrosive and can easily cause equipment corrosion. Some spraying equipment is installed in containers such as boxes to reduce dust and sodium carbonate solution pollution and corrosion. However, since different tunnels require different spraying heights, dust adhesion and sodium carbonate corrosion still exist on the protruding parts of the equipment during spraying, affecting the overall lifespan of the equipment.

[0030] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0031] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0032] Example 1,

[0033] Reference Figure 1-3 This embodiment provides a container component, including:

[0034] The container 1 includes a container body 11, and an outlet 12 is provided on the container body 11.

[0035] Sheath 2 includes a corrugated pipe 21 fixed at one end to outlet 12. An opening 22 is provided at the end of the corrugated pipe 21 away from outlet 12. An abutment part 23 is provided between the opening 22 and the corrugated pipe 21.

[0036] A protective sleeve 2 is installed at the outlet 12 of the housing 11 to protect the equipment passing through the outlet 12 from being contaminated or corroded by the substances inside the housing 11 or the external environment of the housing 11. Specifically, the working part of the equipment extends out or into the housing 11 through the opening 22, and the corrugated pipe 21 extends as the equipment extends in or out to protect the non-working part.

[0037] The abutment part 23 is made of non-elastic material. After the working part of the equipment passes through the opening 22, other parts of the equipment can push the abutment part 23 to drive the bellows 21 to extend, so as to adapt to different insertion or extension lengths of the equipment. The bellows 21 is made of elastic material, which helps the bellows 21 to retract and reset after it is extended.

[0038] Reference Figure 1-3 as well as Figure 6In practical applications, the container 1 of this application can be used for fluid sampling or detection. In this application, the sheath 2 is located inside the container 11, which stores the fluid. The sampling or detection device has a head 81 (working part, i.e., the sampling or detection part) and a telescopic part 82 that drives the head 81 to extend into the container 11. Specifically, the head 81 passes through the opening 22, and the end of the telescopic part 82 near the head 81 abuts against the abutment part 23. As the telescopic part 82 drives the head 81 to extend into the container 11, the telescopic part 82 squeezes the abutment part 23, causing the bellows 21 to extend accordingly, while simultaneously sealing the opening 22, forming a seal on the telescopic part 82. To protect the fluid inside the housing 11 from contacting the telescopic part 82 and causing contamination or corrosion, after the head 81 comes into contact with the fluid, testing or sampling is performed. After sampling or testing, the telescopic part 82 drives the head 81 to extend, and the bellows 21 retracts and resets due to elasticity. To prevent the telescopic part 82 and the abutment part 23 from disengaging during the extension and retraction of the head 81, causing the opening 22 to open, a cooperating adhesive or adsorption structure, such as a magnetic adsorption component, can be provided between the abutment part 23 and the telescopic part 82 to ensure the seal at the opening 22 during the extension. When not sampling or testing, a sealing plug can be provided at the outlet 12 to ensure the airtightness of the storage space.

[0039] Preferred, refer to Figure 1 and Figure 4-5 The end of the bellows 21 away from the outlet 12 is provided with an elastic part 24. The elastic part 24 and the bellows 21 are coaxially arranged. The elastic part 24 has multiple opening lines 25 extending radially from the center to the outer edge.

[0040] The elastic part 24 is specifically sealed at the opening 22 to reduce the interaction between the inside and outside environment of the housing 11. Specifically, the elastic part 24 is sealed at the opening 22, so that the opening 22 is closed. Since the elastic part 24 has multiple radially arranged opening lines 25, the equipment squeezes the elastic part 24, so that the opening lines 25 open, thereby opening the opening 22 without affecting the passage of the equipment. After use, the equipment retracts, releasing the squeeze on the elastic part 24. The elastic part 24 deforms and resets, and the opening lines 25 close again, so that the opening 22 is closed.

[0041] Preferred, refer to Figure 2 or Figure 4 The bellows 21 is a flared shape with its inner diameter gradually decreasing from one end near the outlet 12 to the other end. The bellows 21 and the outlet 12 are coaxially arranged. The inner diameter of the end of the bellows 21 near the outlet 12 is greater than or equal to the aperture of the outlet 12. The end of the bellows 21 near the outlet 12 is turned outward to form a fixing part 26, which is fixed to the housing 11.

[0042] The corrugated pipe 21 is designed in the shape of a flared mouth to fit conventional telescopic structures, such as telescopic rod 31. The end of the corrugated pipe 21 is turned outward to form a fixing part 26. The sheath 2 is fixed to the housing 11 by the fixing part 26. The specific fixing method can be bolt fixing, welding, adhesive bonding, etc., depending on the specific use environment and material.

[0043] Example 2,

[0044] Reference Figure 7 In another application, the sheath 2 is located outside the housing 11, such as in a spraying mechanism that includes the aforementioned container assembly, and also includes...

[0045] The nozzle assembly 3 includes a telescopic rod 31 vertically installed inside the housing 11. A nozzle 32 is installed at the upper end of the telescopic rod 31. A retaining ring 33 is installed on the telescopic rod 31 near the nozzle 32. The outer diameter of the retaining ring 33 is larger than the aperture of the opening 22. The outlet 12 is located directly above the nozzle 32.

[0046] The above-mentioned spraying mechanism also includes a material storage assembly 4, a feeding assembly 5 and a hose reel assembly 6 disposed inside the housing 11;

[0047] The material storage assembly 4 includes a material cylinder 41;

[0048] The feeding assembly 5 includes a feeding pipe 51, one end of which extends into the material cylinder 41 and the other end of which is fixed to the nozzle 32. A driving component 52 is provided on the feeding pipe 51.

[0049] The hose reel assembly 6 includes an electric hose reel 61, on which the feed hose 51 is at least partially wound.

[0050] The specific working method of this spraying mechanism is as follows: The material to be sprayed, such as powder or liquid, is stored in the material cylinder 41. When it is powder, the drive component 52 uses a powder pump; when it is liquid, the drive component 52 uses a liquid pump. When spraying is required, the telescopic rod 31 drives the nozzle 32 to move upward, and at the same time, the electric hose reel 61 releases the hose. After the nozzle 32 extends out of the opening 22, the retaining ring 33 abuts against the abutment part 23. As the telescopic rod 31 continues to move upward, it drives the corrugated pipe 21 to extend and protect the outside of the telescopic rod 31 until the nozzle 32 moves upward to the spraying height. The drive component 52 then works, conveying the material to be sprayed from the material cylinder 41 to the nozzle 32 and spraying it out. After spraying is completed, the drive component 52 stops working, the telescopic rod 31 drives the nozzle 32 to descend and reset, and at the same time, the electric hose reel 61 retracts the hose. The corrugated pipe 21 descends and resets due to the action of elasticity and gravity.

[0051] In this embodiment, the opening 22 of the sheath 2 is sealed by an elastic part 24 with an opening line 25, so that the opening 22 has a certain degree of sealing, which does not affect the extension of the nozzle 32, while reducing the entry of external pollutants into the housing 1.

[0052] Example 3,

[0053] Reference Figure 8-9 This embodiment provides a tunnel hazardous gas treatment vehicle, including an upper spraying mechanism, and also includes a vehicle body 7, with a box 11 disposed on the vehicle body 7.

[0054] Since the main harmful gases during tunnel construction are carbon monoxide and hydrogen sulfide, in this embodiment, the housing 11 has two nozzle assemblies 3: one for spraying hogalat powder particles to treat carbon monoxide, and the other for spraying sodium carbonate solution to treat hydrogen sulfide. The corresponding storage assembly 4, feeding assembly 5, and hose reel assembly 6 are all provided in two sets. At the same time, a third storage assembly 4 can also be provided in the housing 11 for storing water. The storage cylinder 41 for storing sodium carbonate solution and the storage cylinder 41 for storing water are connected to the same drive unit 52 through the feeding pipe 51 and the three-way valve 53. After carbon monoxide treatment, water mist can be sprayed using the nozzle 32 for spraying ammonium carbonate solution to quickly reduce dust.

[0055] With the development of intelligent technology, intelligent monitoring and processing equipment has been realized. In this embodiment, the vehicle body 7 can be equipped with detection equipment for carbon monoxide and hydrogen sulfide and an intelligent control system to realize the integrated detection and processing function of the treatment vehicle, reduce human intervention and reduce risks.

[0056] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
