Description

Technical Field

[0001] This utility model relates to the field of hazardous gas detection technology, specifically to a hazardous gas detector installation mechanism. Background Technology

[0002] Geothermal power plants are power generation facilities that utilize the thermal energy of underground hot water and steam to convert it into mechanical energy, and then into electrical energy. The Earth's interior contains vast amounts of thermal energy, and geothermal power plants extract this underground hot water and steam to the surface using technologies such as drilling. These geothermal fluids are typically high in temperature and possess a large amount of thermal energy. The high-temperature geothermal fluids are introduced into the power plant's steam generator or directly into the steam turbine, driving the turbine to rotate and converting the thermal energy into mechanical energy. The turbine is connected to a generator, and its rotational motion drives the generator's rotor to cut magnetic field lines in a magnetic field, thereby generating electrical energy.

[0003] Although geothermal power plants are considered an environmentally friendly method of power generation, geothermal fluids contain many non-condensable gases (NCG). One of these hazardous gases is hydrogen sulfide, which has a strong rotten egg odor and is highly toxic. Low concentrations can irritate the respiratory tract and eyes, while high concentrations can cause asphyxiation and even death. Hydrogen sulfide is also highly corrosive and can cause serious damage to equipment.

[0004] Therefore, during the operation of a geothermal power plant, it is necessary to use hazardous gas detectors in key areas such as geothermal wellheads, near steam pipes, machine rooms, around heat exchangers, and near equipment where gas leaks may occur, to promptly detect the aforementioned hazardous gases. A commonly used and widely applied hazardous gas analyzer is the Honeywell XCD hydrogen sulfide detector, which can detect toxic and harmful gases such as hydrogen sulfide and carbon monoxide. Its structure is as follows... Figure 1 As shown, the hydrogen sulfide detector 101 has four rectangular mounting holes. During installation at a power plant, a base is typically fixed to the ground, and a riser is welded to the base. A rectangular mounting plate 102 is welded to the top of the riser. Four through holes are pre-drilled on the rectangular mounting plate 102 at the positions corresponding to the four mounting holes on the hydrogen sulfide detector 101. The hydrogen sulfide detector 101 is then fixed to the rectangular mounting plate 102 using bolts 103 and nuts. While this installation method is simple, once the rectangular mounting plate and riser are welded and fixed, the overall position is determined, i.e., the installation angle of the hydrogen sulfide detector is fixed. However, construction workers will consider the actual installation conditions at the construction site, which may lead to discrepancies between the construction drawings and the actual construction scenario, requiring adjustments to the installation height or angle of the hydrogen sulfide detector. Clearly, the current installation method cannot meet these requirements. Utility Model Content

[0005] The purpose of this utility model is to provide a mounting mechanism for a hazardous gas analyzer, so as to solve the technical problem that the existing mounting structure cannot achieve the adjustment of the height and angle of the detector.

[0006] To solve the above problems, the present invention provides a hazardous gas analyzer mounting mechanism with the following technical solution:

[0007] A hazardous gas detector mounting mechanism includes a base and a vertically connected riser on the base, a columnar mounting tube and two fixing components. The columnar mounting tube is detachably connected to the riser. The fixing components are provided with arc-shaped grooves adapted to the shape of the columnar mounting tube. Each fixing component has through holes on both sides of the arc-shaped groove. The through holes are used to correspond to the fixing holes on the hazardous gas detector for inserting fixing bolts. Fixing nuts are threaded onto the fixing bolts at the positions of the fixing components.

[0008] Beneficial effects: This utility model features a detachable connection between the columnar mounting tube and the riser, allowing adjustment of the mounting height of the columnar mounting tube relative to the riser, thereby adjusting the mounting height of the hazardous gas detector. Furthermore, because the fixing component has an arc-shaped groove, and the surface of the columnar mounting tube is also arc-shaped, the fixing component can be engaged at different positions on the surface of the columnar mounting tube. The hazardous gas detector is then mounted on the fixing component via fixing bolts, meaning the mounting angle of the hazardous gas detector can be adjusted. This utility model's installation mechanism can handle complex construction site conditions and is highly versatile.

[0009] Furthermore, the axis of the columnar mounting tube is parallel to the riser.

[0010] Beneficial effect: It can save horizontal installation space.

[0011] Furthermore, the fastener has a weight-reducing elongated hole, the extension direction of which is the same as the length direction of the fastener, and the fastener has at least one through hole on each side of the weight-reducing elongated hole.

[0012] Beneficial effects: While ensuring the normal strength of the fastener, the weight of the fastener is reduced, saving materials.

[0013] Furthermore, the fastener has two through holes on each side of the weight-reducing elongated hole, with the two through holes on the same side of the weight-reducing elongated hole arranged at intervals.

[0014] Beneficial effects: It can be used with hazardous gas detectors of different sizes, thus expanding its application range.

[0015] Furthermore, the distance between the two perforations on both sides of the weight-reducing long hole is equal.

[0016] Furthermore, the fastener is a channel steel, comprising two parallel channel sidewalls and a channel bottom wall connected between the two channel sidewalls. The weight-reducing elongated hole and the through hole are both opened on the channel bottom wall, and the arc-shaped slot is opened on the two channel sidewalls.

[0017] Beneficial effects: The fastener is made of channel steel, which is high in strength, low in cost and light in weight. It has two clamping contact points with the columnar mounting tube, which can ensure the secure fixation of the hazardous gas detector.

[0018] Furthermore, a connecting sleeve is formed on the side of the bottom wall of the groove facing away from the columnar mounting tube at each perforation position. The connecting sleeve has an internal threaded hole that communicates with the perforation and is threadedly engaged with the fixing bolt. The fixing nut is press-fitted onto the end of the connecting sleeve.

[0019] Beneficial effect: Improves the stability of the hazardous gas detector.

[0020] Furthermore, the two corners of the sidewall of the groove away from the bottom wall of the groove are provided with arc-shaped chamfers.

[0021] Beneficial effect: It avoids scratching construction workers due to the sharp corners of the groove sidewalls during installation, thus helping to ensure the safety of construction workers.

[0022] Furthermore, the riser is a cylindrical tube, and a groove extending in the vertical direction is provided on the side wall of the riser. A pin that slides in cooperation with the groove is connected to the cylindrical mounting tube. The riser and the cylindrical mounting tube are detachably connected by two circular clamps.

[0023] Beneficial effect: Facilitates the vertical adjustment of the columnar mounting tube.

[0024] Furthermore, the base includes a seat plate and four stiffening plates welded to the top of the seat plate and evenly distributed around the circumference. The four stiffening plates form a limiting cavity, and the riser is inserted into the limiting cavity. The outer wall of the riser is in contact with each stiffening plate.

[0025] Beneficial effects: During installation, the riser can be stabilized simply by inserting it into the limiting cavity, and there is no need to weld the riser to the various stiffening plates. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0035] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0036] Embodiment 1 of the hazardous gas detector installation mechanism provided by this utility model:

[0037] like Figure 2 and Figure 4 As shown, the installation mechanism of the hazardous gas detector includes a base 1, a riser 2, a columnar mounting tube 3, and two fixing parts 4.

[0038] Among them, such as Figure 4 and Figure 5 As shown, the base 1 includes a base plate 15 and a stiffening plate 13 welded to the top of the base plate 15. The base plate 15 is a rectangular plate, and the stiffening plate 13 is a right-angled triangular plate. Four stiffening plates 13 are evenly distributed around the top of the base plate 15, and the four stiffening plates 13 form a limiting cavity 14.

[0039] The riser 2 is a cylindrical tube that is vertically inserted into the aforementioned limiting cavity 14. The outer wall of the riser 2 is in contact with the supporting ribs 13. The overall height of the riser 2 is sufficient to allow it to stand stably on the base plate 15 without being welded to the ribs 13. Of course, in other embodiments, if the riser 2 is long, the bottom end of the riser 2 can be welded and fixed to the four ribs 13.

[0040] like Figure 4 As shown, a groove extending vertically is provided on the side wall of the riser 2. A pin 12, which slides in the groove, is welded onto the columnar mounting pipe 3. The length of the pin 12 is less than the inner diameter of the riser 2. At this time, the axis of the columnar mounting pipe 3 is parallel to the axis of the riser 2. The construction personnel can adjust the installation height of the hazardous gas detector 6 by moving the columnar mounting pipe 3 up and down. Since both the riser 2 and the columnar mounting pipe 3 are cylindrical, in this embodiment, two circular clamps are respectively clamped on the outside of the riser 2 and the columnar mounting pipe 3 to facilitate their fixation. Then, the two circular clamps are fixed with bolts to achieve a detachable connection between the riser 2 and the columnar mounting pipe 3.

[0041] like Figure 2 As shown, both fasteners 4 are horizontally arranged and perpendicular to the columnar mounting tube 3. In this embodiment, the fastener 4 is a channel steel, including two parallel channel sidewalls and a channel bottom wall connecting the two channel sidewalls. Corresponding arc-shaped slots 5 are provided on the two channel sidewalls, and the arc-shaped slots 5 are adapted to the shape of the columnar mounting tube 3, allowing the fastener 4 to be secured to the columnar mounting tube 3. Two through holes are symmetrically arranged on both sides of the arc-shaped slots 5 on the channel bottom wall, with equal spacing between the two through holes on each side. A weight-reducing elongated hole 9 is provided on the channel bottom wall at the position corresponding to the arc-shaped slot 5. The weight-reducing elongated hole 9 reduces the weight of the fastener 4 without affecting its strength. The through holes are arranged to correspond to the fixing holes on the hazardous gas detector 6. A connecting sleeve 10 is formed at each through hole position on the side of the channel bottom wall facing away from the columnar mounting tube 3. The connecting sleeve 10 has an internal threaded hole that communicates with the through hole and is threadedly engaged with the fixing bolt 7. In actual installation, a long fixing bolt 7 is passed through the fixing hole on the hazardous gas detector 6, the perforation on the bottom wall of the tank, and the connecting sleeve 10. Then, a fixing nut 8 is threaded onto the fixing bolt 7. The fixing nut 8 is pressed onto the end of the connecting sleeve 10, thus realizing the installation and fixing of the hazardous gas detector 6.

[0042] The two corners of the sidewall of the trough away from the bottom wall are provided with arc-shaped chamfers 11, which makes it less likely to scratch the construction workers during installation and improves the safety of the construction workers.

[0043] In actual construction, the installation height of the columnar mounting tube 3 can be adjusted by tightening or loosening the circular clamps, thereby adjusting the installation height of the hazardous gas detector 6. If adjusting the columnar mounting tube 3 still does not meet the installation height requirement, the hazardous gas detector 6 and the fixing component 4 can be slid upwards by tightening or loosening the fixing bolts 7. At this time, the arc-shaped groove 5 and the columnar mounting tube 3 can slide together. After reaching the installation height, the fixing nut 8 can be tightened. Similarly, the installation angle of the hazardous gas detector 6 can be adjusted by rotating the fixing component 4.

[0044] The installation mechanism of this utility model's hazardous gas detector has a simple structure, is easy to install and adjust, and can adapt to the complex construction environment at the construction site.

[0045] Embodiment 2 of the rolling apparatus for producing three-sided ribbed steel bars provided by this utility model:

[0046] Its main difference from Example 1 is:

[0047] In Example 1, the axis of the columnar mounting pipe is parallel to the axis of the riser.

[0048] In this embodiment, as Figure 3 As shown, the axis of the columnar mounting pipe 3 is perpendicular to the axis of the riser pipe 2, and the fixing part 4 is still perpendicular to the columnar mounting pipe 3.

[0049] Based on the above description in this specification, those skilled in the art will also understand that terms used, such as "upper," "lower," "horizontal," "vertical," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not imply that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
