Description

Technical Field

[0001] This invention relates to the field of fire pump technology, specifically to a disassembly-friendly fire pump and its processing and positioning equipment. Background Technology

[0002] As the core power equipment of a fire protection system, fire pumps are mainly used to provide a stable and continuous high-pressure water source for the fire protection pipe network, and are a key device to ensure effective control and suppression of fires in their early stages. The reliability of their performance and the ease of installation and maintenance directly affect the emergency response efficiency and operational safety of the entire fire protection system.

[0003] In existing technologies, fire pumps are generally installed using on-site fixing. Specifically, after the fire pump arrives at the construction site, its base hole positions are measured and drilled in the ground, and then expansion bolts are used to secure the pump body base to the concrete foundation. This traditional installation method has gradually revealed the following prominent problems in practical applications: 1. The installation process is limited by the arrival time of the equipment. Since on-site positioning and drilling can only be carried out after the fire pump is actually in place, it is impossible to pre-construct and install the base or supporting structures. This not only makes the fire pump installation a critical node in the overall fire protection engineering construction process, which is easily affected by equipment delivery delays or site conditions, but also makes the installation work highly dependent on site conditions and the precision of personnel operation, resulting in low installation efficiency. 2. While expansion bolts provide strong connection strength, the disassembly process is extremely cumbersome when fire pumps need maintenance, replacement, or system modification. Expansion bolts may corrode or seize after long-term use, often requiring destructive methods such as cutting and hammering for disassembly. This is not only labor-intensive and time-consuming but also easily damages the pump base and ground foundation, affecting the accuracy and reliability of subsequent reinstallation. Furthermore, in emergency situations, the inconvenience of disassembly can delay repair time. Summary of the Invention

[0004] This invention provides a detachable fire pump and its processing and positioning equipment, which can solve the problems of the existing fire pumps that use on-site drilling and expansion bolt fixing methods, which result in the inability to perform the installation process in advance, low efficiency, and extremely cumbersome and inconvenient disassembly during later maintenance or replacement.

[0005] The objective of this invention can be achieved through the following technical solutions: The first aspect of the present invention provides a detachable fire pump, including a pump body and a chassis located at the bottom of the pump body. A base with mounting holes is provided below the chassis. A plurality of circumferentially evenly distributed shell parts are welded to the top of the base. An arc-shaped enclosure is welded between the side walls of two adjacent shell parts near their ends, and the plurality of arc-shaped enclosures and the plurality of shell parts together form an annular area for accommodating the chassis. An elastic clip is installed inside the shell. A corresponding slot is provided on the curved side wall of the chassis for the elastic clip to be engaged. When the pump body is rotated, the elastic clip can be fully squeezed into the shell part through the slot. A latch is provided at the top of the arc-shaped enclosure. A limiting block corresponding to the latch is hinged on the chassis. When the elastic clip is engaged with the latch, the limiting block corresponds to the position of the latch.

[0006] As a further aspect of the present invention: the elastic clip includes a first spring, a slider, and a pressing block. The slider is slidably disposed inside the housing, and the slider is connected to the inner end of the housing through the first spring. The pressing block is connected to the end of the slider away from the first spring, and the pressing block is located on the outside of the housing. The top and both sides of the pressing block are arranged with an arc surface structure.

[0007] As a further aspect of the present invention: an annular opening corresponding to the annular area is opened at the center of the base, and a rotatable turntable is installed inside the annular opening, the top of the turntable being flush with the top of the base.

[0008] The second aspect of the present invention provides a processing and positioning device for a portable fire pump, used for processing and positioning the aforementioned portable fire pump. The device includes a processing table for placing a base, and a plurality of carriers for placing the housing are provided above the processing table. A support and suction mechanism is installed between the carriers and the processing table, and the support and suction mechanism is used to draw the inner cavity of the carrier to a negative pressure state, thereby positioning and adsorbing the housing. A first driving unit is installed on the processing table to drive the carriers to deflect, and after the carriers deflect, they position and press the housing against the top of the base. An elastic abutment is rotatably provided on the processing table adjacent to the carriers. A second driving unit is installed on the processing table to drive the elastic abutment to rotate, and after the elastic abutment rotates, it is used to press an arc-shaped enclosure between two adjacent carriers.

[0009] As a further embodiment of the present invention: the carrier includes a shell, an L-shaped column, an adsorption hole, a rotating shaft, and an air intake valve. The shell is open at one end, and the two L-shaped columns are symmetrically connected at the end of the shell away from the opening. Both the shell and the L-shaped column are hollow structures, and the inner cavity of the L-shaped column is connected to the inner cavity of the shell. The plurality of adsorption holes are evenly arranged on the inner sidewall of the shell and are connected to its inner cavity. The rotating shaft is installed between the opposing sidewalls of the two L-shaped columns at the end away from the shell, and the air intake valve is installed on the sidewall of the shell.

[0010] As a further embodiment of the present invention: the supporting air extraction mechanism includes a fixing ring, a column, a convex tube, and an air extraction pipe. The fixing ring is fitted onto the side wall of the processing table. The two columns are symmetrically arranged on opposite sides of the two L-shaped columns. Both the columns and the fixing ring are hollow structures, and the columns and the air extraction pipe are connected and installed on the top of the fixing ring. The convex tube is connected and installed on the side of the column near the top, and the convex tube is coaxial with the rotating shaft. The other end of the convex tube is rotatably connected to the side wall of the L-shaped column away from the housing through a sealed bearing, and the convex tube is connected to the inner cavity of the L-shaped column.

[0011] As a further embodiment of the present invention: the first drive unit includes a cylinder, a movable ring, a connecting frame, a guide post, a rack, and a first gear. The first gear is mounted on a rotating shaft and meshes with the rack. The guide post is connected to the bottom end of the rack, and the bottom end of the guide post slides through the processing table and is connected to the movable ring. The connecting frame is connected inside the movable ring. The cylinder is located at the bottom of the processing table and is used to drive the connecting frame to rise and fall.

[0012] As a further aspect of the present invention: the elastic abutment includes an outer column, an inner column, a second spring, and a pivot pin. The inner column is slidably inserted into the outer column, and the inner column and the outer column are connected by the second spring. The pivot pin is installed at the bottom of the outer column, and the pivot pin passes through the processing table and is rotatably connected to it.

[0013] As a further embodiment of the present invention: the second drive unit includes a stepper motor, a mounting bracket, a second gear, an internal gear ring, and a rotating ring. The rotating ring is rotatably mounted on the support suction mechanism. The internal gear ring is mounted on the inner side wall of the rotating ring near the bottom end. The second gear is mounted on the bottom end of the rotating pin and meshes with the internal gear ring. The stepper motor is coaxially connected to the bottom end of one of the rotating pins, and the stepper motor is connected to the bottom of the processing table through the mounting bracket.

[0014] As a further aspect of the present invention: the carrier further includes a verification post to prevent the shell from being placed upside down, the verification post having an L-shaped structure, and one end of the verification post being connected to the opening end of the shell.

[0015] The beneficial effects of this invention are: 1. In this invention, by setting a base that can be separated from the pump chassis, the base can be pre-fixed to the installation ground through mounting holes, thus transforming the traditional "simultaneous installation after the pump arrives on site" mode into a two-stage mode of "pre-installation of the base and subsequent assembly of the pump." This allows the positioning and fixing of the base to be completed before the fire pump arrives on site, significantly shortening the waiting time for on-site installation and the overall construction period, and improving the flexibility and efficiency of construction organization. At the same time, the pre-welded annular positioning structure composed of multiple shell parts and arc-shaped barriers on the base provides precise accommodation space for the pump chassis, ensuring the convenience and accuracy of final on-site assembly, fundamentally overcoming the drawback of existing technologies where installation procedures cannot be performed in advance.

[0016] 2. In this invention, the rapid locking and releasing of the fire pump is achieved through the cooperation of an elastic locking element integrated within the housing and a slot on the side wall of the chassis, combined with the circumferential rotation of the pump body. During installation, simply place the pump chassis into the annular area and rotate it. After rotating to the predetermined position, the elastic locking element automatically engages with the slot under its own elastic force. Simultaneously, the hinged limiting block on the chassis falls into the slot of the arc-shaped enclosure, achieving circumferential positioning. During disassembly, rotating the pump body in the opposite direction forces the slot to expel the elastic locking element, thereby releasing the lock. The entire process requires no tools, greatly simplifying the disassembly process and avoiding the problems of traditional expansion bolts being difficult to disassemble after corrosion or causing damage to the foundation during disassembly. This provides unprecedented convenience for the daily maintenance, emergency repair, or complete replacement of the fire pump.

[0017] 3. In this invention, a dedicated processing and positioning device is provided. This device utilizes the negative pressure generated by the supporting suction mechanism, in conjunction with the carrier components, to conveniently adsorb and position each independent shell component. Subsequently, the first drive unit drives all carrier components to rotate synchronously and precisely, pressing the adsorbed shell components tightly and stably onto the welding position on the base, ensuring the consistency of the fit between the bottom of all shell components and the top surface of the base, as well as the consistency of the welding gap. Simultaneously, the second drive unit drives the elastic abutment components located between adjacent carrier components to rotate, firmly pressing the arc-shaped enclosure between the corresponding two shell components from the side. This ensures that the final welded annular area has high dimensional accuracy, shape consistency, and structural strength, guaranteeing the assembly quality, reliability, and interchangeability of the easy-to-disassemble fire pump product from the manufacturing source.

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figures 1-3As shown, the present invention is a portable fire pump, including a pump body 100 and a chassis 101 located at the bottom of the pump body 100. A base 200 with mounting holes 201 is provided below the chassis 101. Multiple circumferentially evenly distributed shell parts 202 are welded to the top of the base 200. An arc-shaped barrier 203 is welded between the sidewalls of two adjacent shell parts 202 near their ends. The multiple arc-shaped barriers 203 and the multiple shell parts 202 together form an annular area to accommodate the chassis 101. The chassis is equipped with... The chassis 101 is equipped with an elastic locking element 300. The curved side wall of the chassis 101 is provided with a corresponding slot 102 for the elastic locking element 300 to be inserted. When the pump body 100 is rotated, the elastic locking element 300 can be fully squeezed into the shell 202 through the slot 102. The top of the arc-shaped enclosure 203 is provided with a slot 204. A limiting block 103 corresponding to the slot 204 is hinged on the chassis 101. When the elastic locking element 300 is engaged with the slot 102, the limiting block 103 and the slot 204 are positioned accordingly.

[0023] It should be noted that during use, the base 200 is pre-fixed to the ground through its mounting holes 201. When the pump body 100 needs to be installed, the operator places the chassis 101 into the annular area formed by multiple shells 202 and the arc-shaped enclosure 203, forcing the elastic locking member 300 to retract completely into the shell 202. Then, the pump body 100 is rotated. When it is rotated to the predetermined position, the elastic locking member 300 pops out under its own elastic force and locks into the slot 102, thereby aligning the pump body 100 with the base. Longitudinal separation is not possible between 200 and 201. At the same time, the limiting block 103 hinged on the chassis 101 can be inserted into the slot 204 of the arc-shaped enclosure 203 to complete circumferential limiting, thereby achieving quick installation. When it is necessary to disassemble the pump body 100, after the limiting block 103 is turned out of the slot 204, the pump body 100 is rotated, and the wall of the slot 102 will push the elastic clip 300 back into the shell 202. The pump body 100 and the chassis 101 can then be lifted upward as a whole to complete the non-destructive and quick disassembly.

[0024] like Figures 2-3 As shown, the elastic clip 300 includes a first spring 301, a slider 302, and a pressing block 303. The slider 302 is slidably disposed inside the housing 202, and the slider 302 is connected to the inner end of the housing 202 by the first spring 301. The pressing block 303 is connected to the end of the slider 302 away from the first spring 301, and the pressing block 303 is located on the outside of the housing 202. The top and both sides of the pressing block 303 are arranged with an arc surface structure.

[0025] It should be noted that when the pump body 100 is installed, the bottom of the chassis 101 applies pressure to the top arc surface of the extrusion block 303, forcing the extrusion block 303 to move into the housing 202. When the pump body 100 is rotated until the slot 102 is fully aligned with the extrusion block 303, the compressed first spring 301 releases its elastic force, pushing the slider 302 and the extrusion block 303 outward, so that the extrusion block 303 is locked into the slot 102. When the pump body 100 is disassembled, the pump body 100 is rotated so that the side wall of the slot 102 applies pressure to the side arc surface of the extrusion block 303, pushing it into the housing 202 again and compressing the first spring 301 until the extrusion block 303 is completely disengaged from the slot 102, thus releasing the lock.

[0026] like Figures 1-2 As shown, an annular opening corresponding to the annular area is opened at the center of the base 200, and a rotatable turntable 205 is installed inside the annular opening. The top of the turntable 205 is flush with the top of the base 200.

[0027] It should be noted that when the pump body 100 rotates during installation or disassembly, its bottom chassis 101 contacts the turntable 205 and drives the turntable 205 to rotate synchronously, thereby converting sliding friction into rolling friction, effectively reducing the frictional resistance between the pump body 100 and the base 200 when rotating, making the rotation operation more effortless and smooth.

[0028] like Figures 3-10 This invention provides a processing and positioning device for a portable fire pump, used for processing and positioning the portable fire pump. It includes a processing table 400 for placing a base 200. To facilitate the positioning of the base 200, in this embodiment, multiple positioning pins corresponding to the mounting holes 201 on the base 200 are installed on the top of the processing table 400. Multiple support members 500 for placing the housing 202 are provided above the processing table 400. A supporting air extraction mechanism 600 is installed between the support members 500 and the processing table 400, and the supporting air extraction mechanism 600 is used to support the support members 502. The inner cavity is drawn to a negative pressure state, thereby positioning and adsorbing the shell 202. A first drive unit 700 is installed on the processing table 400 to drive the bearing 500 to deflect. After the bearing 500 deflects, it positions and presses the shell 202 against the top of the base 200. An elastic abutment 800 is rotatably arranged on the processing table 400 of the adjacent bearing 500. A second drive unit 900 is installed on the processing table 400 to drive the elastic abutment 800 to rotate. After the elastic abutment 800 rotates, it is used to press the arc-shaped enclosure 203 against the two adjacent bearings 500.

[0029] It should be noted that during use, the base 200 is first placed on the processing table 400, and multiple shell parts 202 are placed on their corresponding support members 500. The support vacuum mechanism 600 is activated to draw the inner cavity of the support member 500 into a negative pressure state, and the shell parts 202 are initially positioned and fixed by the negative pressure adsorption. Then, the first drive unit 700 drives the support member 500 to deflect, causing the support member 500 to carry the shell parts 202 downwards and accurately position and press the shell parts 202 against the preset welding position on the top of the base 200. Then, the arc-shaped enclosure 203 is placed on the corresponding... At the top position of the base 200 between adjacent shell parts 202, the second drive unit 900 drives the elastic abutment 800 set between adjacent support parts 500 to rotate. After the elastic abutment 800 rotates, it presses the arc-shaped enclosure 203 against the two adjacent support parts 500 from the side. This not only completes the precise positioning of the shell part 202 and the arc-shaped enclosure 203 on the base 200, providing a precise and stable assembly foundation for subsequent welding processes, but also ensures that the shell part 202, the base 200, and the arc-shaped enclosure 203 are always in a tight abutment state, improving the subsequent welding effect.

[0030] like Figures 5-6 As shown, the carrier 500 includes a housing 501, an L-shaped column 502, an adsorption hole 503, a rotating shaft 504, and an air intake valve 505. The housing 501 is open at one end, and two L-shaped columns 502 are symmetrically connected at the end of the housing 501 away from the opening. Both the housing 501 and the L-shaped column 502 are hollow structures, and the inner cavity of the L-shaped column 502 is connected to the inner cavity of the housing 501. Multiple adsorption holes 503 are evenly arranged on the inner sidewall of the housing 501 and are connected to its inner cavity. The rotating shaft 504 is installed between the opposing sidewalls of the two L-shaped columns 502 at the end away from the housing 501. The air intake valve 505 is installed on the sidewall of the housing 501.

[0031] It should be noted that when the shell 202 is placed into the shell cover 501 from the open end, the supporting air extraction mechanism 600 extracts the internal air to form a negative pressure through the inner cavity of the L-shaped column 502 and the inner cavity of the shell cover 501. The negative pressure acts on the outer surface of the shell 202 through multiple adsorption holes 503 evenly distributed on the inner side wall of the shell cover 501, thereby firmly adsorbing it into the shell cover 501 for positioning. The bearing 500 achieves overall deflection through the rotating shaft 504 connecting the two L-shaped columns 502. When it is necessary to separate the shell cover 501 from the welded shell 202, the external air can be introduced by opening the air inlet valve 505 to quickly release the negative pressure state.

[0032] like Figures 5-7As shown, the supporting suction mechanism 600 includes a fixing ring 601, a column 602, a convex tube 603, and a suction pipe 604. The fixing ring 601 is fitted onto the side wall of the processing table 400. Two columns 602 are symmetrically arranged on opposite sides of two L-shaped columns 502. Both the column 602 and the fixing ring 601 are hollow structures, and the column 602 and the suction pipe 604 are connected and installed on the top of the fixing ring 601. The convex tube 603 is connected and installed on the side of the column 602 near the top, and the convex tube 603 is coaxially arranged with the rotating shaft 504. The other end of the convex tube 603 is rotatably connected to the side wall of the L-shaped column 502 away from the housing 501 through a sealed bearing, and the convex tube 603 is connected to the inner cavity of the L-shaped column 502.

[0033] It should be noted that the external suction device draws air through the suction pipe 604. The airflow passes sequentially through the hollow fixed ring 601, the hollow column 602, and the convex pipe 603 connected to it, and enters the inner cavity of the L-shaped column 502 through the connection between the convex pipe 603 and the L-shaped column 502, finally reaching the inner cavity of the shell 501. Through continuous suction, a stable negative pressure is formed in the inner cavity of the shell 501. This negative pressure acts on the outer surface of the shell 202 through the evenly distributed adsorption holes 503, thereby firmly adsorbing and positioning it. The convex pipe 603 and the rotating shaft 504 of the carrier 500 are coaxially designed and are rotatably connected to the L-shaped column 502 through a sealed bearing. This structure ensures that no matter how the carrier 500 is deflected under the drive, its internal suction channel always remains connected and sealed, so that the negative pressure adsorption state can be continuously maintained during dynamic adjustment.

[0034] like Figures 5-6 and Figure 8 As shown, the first drive unit 700 includes a cylinder 701, a movable ring 702, a connecting frame 703, a guide post 704, a rack 705, and a first gear 706. The first gear 706 is mounted on the rotating shaft 504 and meshes with the rack 705. The guide post 704 is connected to the bottom end of the rack 705, and the bottom end of the guide post 704 slides through the processing table 400 and is connected to the movable ring 702. The connecting frame 703 is connected inside the movable ring 702. The cylinder 701 is located at the bottom of the processing table 400 and is used to drive the connecting frame 703 to rise and fall.

[0035] It should be noted that the cylinder 701 drives the connecting frame 703 to move up and down. The connecting frame 703 drives the movable ring 702 connected to it to move up and down synchronously. The movable ring 702 drives the rack 705 to move in the vertical direction through the guide column 704. The linear motion of the rack 705 is converted into rotational motion through the first gear 706 meshing with it, thereby driving the rotating shaft 504, which is coaxially mounted with the first gear 706, to rotate. Finally, the synchronous deflection action of all the bearings 500 mounted on the rotating shaft 504 is achieved.

[0036] like Figure 5 and Figures 9-10 As shown, the elastic abutment 800 includes an outer post 801, an inner post 802, a second spring 803, and a pivot pin 804. The inner post 802 is slidably inserted into the outer post 801, and the inner post 802 and the outer post 801 are connected by the second spring 803. The pivot pin 804 is installed at the bottom of the outer post 801, and the pivot pin 804 passes through the processing table 400 and is rotatably connected to it.

[0037] It should be noted that when the second drive unit 900 drives the pivot pin 804 to rotate, the pivot pin 804 drives the outer column 801, which is fixedly connected to it, to rotate as a whole. When the end of the inner column 802 contacts the side wall of the arc-shaped enclosure 203 during the rotation, as the outer column 801 continues to rotate, the inner column 802 will slide relative to the outer column 801 and compress the second spring 803, thereby applying continuous pressure to the top of the inner column 802 on the side wall of the arc-shaped enclosure 203. In this embodiment, the maximum rotation stroke of the outer column 801 is reached when the inner column 802 is perpendicular to the tangent of the arc-shaped enclosure 203.

[0038] like Figure 5 and Figure 9 As shown, the second drive unit 900 includes a stepper motor 901, a mounting bracket 902, a second gear 903, an internal gear ring 904, and a rotating ring 905. The rotating ring 905 is rotatably mounted on the support suction mechanism 600. The internal gear ring 904 is mounted on the inner side wall of the rotating ring 905 near the bottom end. The second gear 903 is mounted on the bottom end of the rotating pin 804 and meshes with the internal gear ring 904. The stepper motor 901 is coaxially connected to the bottom end of one of the rotating pins 804, and the stepper motor 901 is connected to the bottom of the processing table 400 through the mounting bracket 902.

[0039] It should be noted that in this embodiment, the rotating ring 905 is rotatably connected to the outer ring of the fixed ring 601 via a bearing. After the stepper motor 901 starts, it directly drives a pivot pin 804 coaxially connected to its output shaft to rotate. The second gear 903 installed at the bottom of the pivot pin 804 rotates accordingly. Since the second gear 903 meshes with the internal gear ring 904 fixedly installed on the inner side wall of the rotating ring 905, the rotation of the second gear 903 will drive it to revolve around the internal gear ring 904, thereby driving the entire rotating ring 905 to rotate along the fixed ring 601. The rotational motion of the rotating ring 905 is transmitted to all other second gears 903 meshing with it through the internal gear ring 904, thereby driving all pivot pins 804 to rotate synchronously and in the same direction. Finally, the synchronous rotation of all elastic abutment members 800 installed on the top of each pivot pin 804 is achieved, so as to complete the operation of simultaneously pressing multiple arc-shaped barriers 203 against the corresponding positions.

[0040] like Figure 4 and Figure 6As shown, the carrier 500 also includes a verification post 506 to prevent the shell 202 from being placed upside down. The verification post 506 has an L-shaped structure, and one end of the verification post 506 is connected to the open end of the shell 501.

[0041] It should be noted that when the operator places the housing 202 into the housing 501, if the housing 202 is incorrectly placed with the arc-shaped surface of the pressing block 303 of the elastic clip 300 facing upwards, the planar structure of the pressing block 303 will interfere with the vertical part of the verification post 506. This will cause the housing 202 to be lifted by the verification post 506 and unable to fully fit against the inner wall of the housing 501, thus alerting the operator to the incorrect placement orientation. Figure 4 For example, only when the shell 202 is placed in the correct direction (i.e., the arc surface of the extrusion block 303 faces the inside of the shell 501) can the extrusion block 303 avoid the interference of the verification column 506, smoothly enter the inside of the shell 501 and completely fit into the inner wall where the adsorption hole 503 is located, and then be effectively adsorbed and positioned by negative pressure, thereby realizing the error prevention function and ensuring that the positioning posture of each shell 202 is consistent and correct before welding.

[0042] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
