Description

Technical Field

[0001] This utility model relates to the field of fire pump technology, specifically to a base for a vertical multi-stage fire pump set. Background Technology

[0002] Vertical multistage fire pumps are common fire-fighting equipment that play an important role in fire prevention. As the importance of vertical multistage fire pumps becomes increasingly prominent, a base is required when fixing and installing them. The base has become an indispensable component of vertical multistage fire pumps.

[0003] A search revealed that prior art CN215862701 U discloses a base for a vertical multistage fire pump set, comprising: a fire pump and a concave base block. The fire pump is installed on the concave base block, which is equipped with a telescopic drainage structure and a movable telescopic fixing structure. The telescopic drainage structure includes: a concave bearing block, a drainage shaft tube, a drainage pipe, a drainage bearing block, a flexible collection pipe, a collection drive motor, and a gearbox. This utility model relates to the field of vertical multistage fire pump technology. The telescopic drainage structure allows for the rotation and collection of the flexible collection pipe. Simultaneously, the cooperation between the drainage bearing block and the drainage pipe prevents the drainage pipe from rotating. The movable telescopic fixing structure allows for vertical lifting and lowering of the entire device, thereby achieving the lifting and telescopic movement of the transport wheels. Furthermore, two pairs of lifting buckets, two pairs of lifting hydraulic cylinders, and two pairs of lifting concave blocks achieve a negative pressure adsorption and fixing effect.

[0004] However, the above equipment has the following problems when in use: no quick-release structure is set when the fire pump and the concave base block are installed and connected. This means that the base of the fire pump needs to be fixed to the concave base block with multiple bolts. During later maintenance and disassembly, the number of bolts makes it difficult to achieve quick disassembly. Utility Model Content

[0005] The purpose of this utility model is to provide a base for a vertical multi-stage fire pump set, which enables quick disassembly during the later maintenance and disassembly of the fire pump body.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a vertical multi-stage fire pump set base, including a fire pump body and a fixing mechanism;

[0007] The fixing mechanism includes a base plate, a mounting platform, positioning pins, locking blocks, a left support arm, a right support arm, a limiting seat, a tensioning screw, and a nut. The base plate is integrally formed with the mounting platform. Four positioning pins are set on the mounting platform and are slidably connected to the fire pump body. The locking blocks are symmetrically arranged and can abut against the fire pump body, with their tops limited by pins. The left and right support arms are detachably connected to the locking blocks, and the limiting seats are detachably connected to the base plate and are symmetrically arranged front and rear. The spacing between the limiting seats is just enough for the fixing parts of the left and right support arms to fit together. The tensioning screw passes through the limiting seat, the left support arm, and the right support arm, respectively. The nut is threadedly connected to the tensioning screw and abuts against the rear limiting seat.

[0008] The fire pump body consists of a pump body, a mounting base, and a drive motor. The mounting base is located on the top of the pump body. The drive motor is mounted on the mounting base. The output shaft of the drive motor is connected to the transmission shaft of the impeller of the pump body via a coupling.

[0009] The fixing mechanism further includes a rectangular plate, which is integrally formed with the locking block and slidably connected to the mounting platform.

[0010] The front limiting seat is provided with a limiting part, the inner cavity of which is hexagonal, to prevent the head of the tensioning screw from rotating.

[0011] The fixing mechanism further includes a slide bar, which is slidably connected to the mounting platform and slidably abuts against one side of the left support arm and the right support arm, respectively.

[0012] This utility model discloses a base for a vertical multi-stage fire pump unit. When disassembling the fire pump body, first remove two pins, then remove the nut and the tensioning screw. At this point, the left and right support arms are completely loosened. Then, the left and right support arms can be removed directly, allowing the two locking blocks to disengage from the fire pump body, thus loosening the fire pump body. Finally, the fire pump body can be lifted upwards and released from the four positioning pins. In this base structure, the pins can be directly removed during fire pump body disassembly. Subsequently, only one nut needs to be removed to remove the tensioning screw. Then, the locking blocks can be completely loosened and removed. Finally, the fire pump body can be directly lifted upwards and removed. Compared to traditional multiple bolt fixation, this application is more convenient to disassemble, thus enabling rapid disassembly during later maintenance of the fire pump body.

Detailed Implementation

[0018] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the base for a vertical multistage fire pump unit. Figure 2 This is a structural schematic diagram of the locking block 105. This utility model provides a base for a vertical multi-stage fire pump unit: it includes a fire pump body 101 and a fixing mechanism. The fixing mechanism includes a base plate 102, a mounting platform 103, a positioning pin 104, a locking block 105, a left support arm 106, a right support arm 107, a limiting seat 108, a tensioning screw 109, a nut 110, and a rectangular plate 112. The fire pump body 101 consists of a pump body 1011, a mounting base 1012, and a drive motor 1013. The aforementioned solution allows for quick disassembly of the fire pump body 101 during later maintenance and disassembly. It is understood that the aforementioned solution facilitates more convenient disassembly of the fire pump body 101 during later stages.

[0021] In this embodiment, a positioning pin hole and a mating pin hole are provided on the base of the pump body 101 at the bottom of the fire pump body 101. The positioning pin hole is used to mate with the four positioning pins 104, and the mating pin hole is used to mate with the latch 111.

[0022] The base plate 102 is integrally formed with the mounting platform 103. Four positioning pins 104 are set on the mounting platform 103 and are slidably connected to the fire pump body 101. The locking blocks 105 are symmetrically arranged and can abut against the fire pump body 101, and their tops are limited by pins 111. The left support arm 106 and the right support arm 107 are detachably connected to the locking blocks 105 respectively. The limiting seats 108 are detachably connected to the base plate 102 and are symmetrically arranged front and rear. The spacing between the limiting seats 108 is just enough for the fixing parts of the left support arm 106 and the right support arm 107 to fit together. The tensioning screw 109 passes through the limiting seats 108, the left support arm 106 and the right support arm 107 respectively. The nut 110 is threadedly connected to the tensioning screw 109 and abuts against the rear limiting seat 108. The mounting platform 103 has four non-through positioning pin holes on its top to facilitate the installation of the four positioning pins 104. The positioning pins 104 can also be integrally formed with the mounting platform 103 to ensure stability. The locking block 105 can fit against both sides of the base at the bottom of the pump body 1011. The top of the locking block 105 has a pin hole to facilitate the insertion of the pin 111. The pin 111 has a U-shaped cross-section. The left support arm 106 and the right support arm 107 are connected to the locking block 105 by countersunk cylindrical pins and bolts, respectively. The fixing parts of the left support arm 106 and the right support arm 107 each have through holes. The limiting seat 108 is fixed by mounting pins and bolts. The tensioning screw 109 has a T-shaped cross-section. The nut 110 can be directly installed on the stepped thread end of the tensioning screw 109 away from its hexagonal head, and after installation, it abuts against the rear limiting seat 108.

[0023] Secondly, the fire pump body 101 consists of a pump body 1011, a mounting base 1012, and a drive motor 1013. The mounting base 1012 is located on the top of the pump body 1011; the drive motor 1013 is mounted on the mounting base 1012; the output shaft of the drive motor 1013 is connected to the drive shaft of the impeller of the pump body 1011 via a coupling. During operation, the drive motor 1013 drives the drive shaft of the multi-stage impeller of the pump body 1011 to rotate, thereby rotating the impeller and pumping water.

[0024] Then, the fixing mechanism further includes a rectangular plate 112, which is integrally formed with the locking block 105 and slidably connected to the mounting platform 103. The bottom of the mounting platform 103 is provided with a through groove to facilitate the sliding of the rectangular plate 112. The rectangular plate 112 is directly integrally formed with the locking block 105, which facilitates quick alignment and engagement of the locking block 105 during installation. When the rectangular plate 112 is in the groove of the mounting platform 103, the left support arm 106 and the right support arm 107 can be attached and located between the limiting seat 108, which is beneficial for the setting of the tensioning screw 109.

[0025] Finally, a limiting part 113 is provided on the front limiting seat 108. The inner cavity of the limiting part 113 is hexagonal, which is used to prevent the head of the tensioning screw 109 from rotating. The limiting part 113 is used to prevent the tensioning screw 109 from rotating, that is, it can prevent the tensioning screw 109 from rotating when the nut 110 is installed or removed. When installing or removing the fire pump body 101, it is not limited to a single person to operate, and the installation or removal operation can be carried out with the cooperation of multiple people.

[0026] When using this invention for quick disassembly during later maintenance of the fire pump body 101, the following steps are performed: First, remove the two pins 111. Next, remove the nut 110 and then the tensioning screw 109. At this point, the left support arm 106 and the right support arm 107 are completely loosened. Then, directly remove the left support arm 106 and the right support arm 107 respectively, allowing the two locking blocks 105 to disengage from the fire pump body 101, thus loosening the fire pump body 101. Finally, the fire pump... The main body 101 can be lifted upwards and disengaged from the four positioning pins 104. In the base structure of this application, when the fire pump main body 101 is disassembled, the pin 111 can be directly removed. Subsequently, only one nut 110 needs to be removed to remove the tensioning screw 109. Then, the locking block 105 can be completely loosened and removed. Finally, the fire pump main body 101 can be lifted upwards and removed directly. Compared with the traditional multiple bolt fixation, the disassembly of this application is more convenient, and thus can be quickly disassembled during the later maintenance and disassembly of the fire pump main body 101.

[0027] Example 2:

[0028] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of the base for a vertical multistage fire pump set. Based on the first embodiment, this utility model provides a base for a vertical multistage fire pump set. The fixing mechanism also includes a slide bar 201, which is slidably connected to the mounting platform 103 and slidably abuts against one side of the left support arm 106 and the right support arm 107, respectively.

[0029] In this embodiment, the mounting platform 103 is provided with vertical, non-penetrating grooves to facilitate the installation or positioning of the slide bar 201. The grooves are symmetrically arranged. After the left support arm 106 and the right support arm 107 are installed, the connecting screw 109 and the nut 110 cooperate to assemble and hold the left support arm 106 and the right support arm 107, and then the slide bar 201 can be directly installed. The slide bar 201 forms an abutment and limiting structure on one side of the left support arm 106 and the right support arm 107 for further limiting, and can be directly slid upwards to remove it later without affecting the ease of operation.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
