Technical Field
[0001] This utility model relates to the field of fire pumps, and in particular to a mobile fire pump. Background Technology
[0002] In today's society, fires occur frequently, posing a significant threat to people's lives and property. Mobile fire pumps, as a key piece of equipment in fire and rescue operations, directly impact the efficiency and effectiveness of firefighting and rescue efforts. In narrow streets, old residential areas, or remote locations, large fire trucks may not be able to reach the fire scene directly. In these situations, mobile fire pumps become crucial firefighting equipment, as they can flexibly move to locations inaccessible to fire trucks, providing essential water support for firefighting operations.
[0003] However, during operation, fire pumps may vibrate due to factors such as pump body vibration and water flow impact. The small contact area between the rollers and the ground makes it difficult to provide stable support, which can easily lead to displacement of the fire pump and affect its operational stability. Once displacement occurs, it can not only cause loosening of the connection between the fire pump and the water source, water hose, and other components, but also cause problems such as water leakage and reduce water supply efficiency. Therefore, a mobile fire pump is proposed to solve the above problems. Utility Model Content
[0004] In order to solve the problems existing in the prior art, the present invention provides a mobile fire pump.
[0005] The mobile fire pump provided by this utility model adopts the following technical solution:
[0006] A mobile fire pump includes a support frame and a pump body disposed inside the support frame. The support frame has a stabilizing mechanism at its bottom, comprising a stabilizing component and a transmission component. The stabilizing component includes four positioning frames, each fixed to one of the four corners of the support frame. A moving block is vertically slidably connected to the center of each positioning frame. A support plate is horizontally slidably connected through the center of each moving block. A roller is mounted on the bottom of the support plate. A second support plate is fixedly connected between the tops of two corresponding positioning frames. A connecting block is hinged between the second support plate and the first support plate. The transmission component includes a guide plate and a driving component for moving the guide plate left and right. The guide plate is fixed between two first support plates.
[0007] By adopting the above technical solution, the drive component drives the guide plate to move laterally, and the guide plate and connecting block drive the support plate to move laterally and vertically at the same time, thereby driving the roller to contact the ground, thus moving the fire pump. Conversely, it causes the roller to leave the ground, maintaining the stability of the fire pump. The mobile fire pump is easy to move and fix, can ensure the stability of the fire pump during operation, and solves the problem of displacement.
[0008] Optionally, a stabilizing block is fixed between two adjacent positioning frames.
[0009] By adopting the above technical solution, the contact area between the fire pump and the ground is increased by setting up stabilizing blocks, thereby improving the overall stability.
[0010] Optionally, the drive assembly includes a servo motor mounted below the support frame. The output end of the servo motor is equipped with a threaded rod, which rotates through the stabilizing block. A push plate slides vertically through the guide plate, and the threaded rod is threaded through the top of the push plate. A positioning plate slides laterally through the bottom of the push plate, and one end of the positioning plate is fixedly connected to the stabilizing block.
[0011] By adopting the above technical solution, the servo motor drives the threaded rod to rotate, the threaded rod drives the push plate to move, the push plate drives the guide plate to move, and the guide plate drives the support plate to move. This drive component can achieve automated operation, with stable performance and simple operation.
[0012] Optionally, the bottom of the support frame is provided with a winding assembly to facilitate the winding of the outwardly extending hose.
[0013] By adopting the above technical solution, the winding assembly can wind up the hose, making it easier for workers to move the fire pump and protecting the hose.
[0014] Optionally, the winding assembly includes fixed blocks mounted on a support frame, two rotating rods coaxially rotatably mounted on the two fixed blocks, a winding roller fixed between the two rotating rods, and a handwheel mounted on one end of one of the rotating rods.
[0015] By adopting the above technical solution, the operator can drive the take-up roller to rotate by simply turning the handwheel. One end of the hose is wrapped around the take-up roller, and then the handwheel is turned. The operation is simple and improves efficiency.
[0016] Optionally, the take-up roller is provided with a slot for inserting a flexible hose.
[0017] By adopting the above technical solution, one end of the hose is inserted into the slot to fix one end of the hose, so that the hose can be wound stably and orderly when the winding roller is rotated, thereby improving the winding quality.
[0018] In summary, this utility model has at least one of the following beneficial technical effects:
[0019] The drive assembly drives the guide plate to move laterally, and the guide plate and connecting block drive the support plate to move laterally and vertically at the same time, thereby driving the roller to contact the ground, thus moving the fire pump. Conversely, it causes the roller to leave the ground, maintaining the stability of the fire pump. This mobile fire pump is easy to move and fix, can ensure the stability of the fire pump during operation, and solves the problem of displacement.
[0020] The installation of stabilizing blocks increases the contact area between the fire pump and the ground, thereby improving the overall stability.
[0021] A servo motor drives a threaded rod to rotate, which in turn drives a push plate to move. The push plate then moves a guide plate, which in turn moves a support plate. This drive assembly enables automated operation, is stable in performance, and is easy to operate. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Reference Figure 1 , Figure 2 and Figure 3The present invention provides an embodiment of a mobile fire pump, comprising a support frame 1 for supporting the pump body 4, a roller 2 for facilitating the movement of the fire pump at the bottom end of the support frame 1, the pump body 4 being the fire pump body itself fixedly installed inside the support frame 1, and a stabilizing mechanism for increasing the stability of the fire pump at the bottom end of the support frame 1, the stabilizing mechanism including a stabilizing component and a transmission component for driving the roller 2 to rise and fall.
[0029] The stabilizing component includes a positioning frame 22 and a stabilizing block 210. Two sets of stabilizing blocks 210 are provided and are respectively located on the bottom left and right sides of the support frame 1. The stabilizing blocks 210 are fixed between two adjacent positioning frames 22. The positioning frames 22 are fixedly connected to the bottom of the support frame 1 and there are four of them. A moving block 211 that stabilizes and drives the support plate 21 to move up and down is slidably connected to the middle of the positioning frame 22.
[0030] Furthermore, a support plate 21 is slidably connected through the middle of the movable block 211 to drive the roller 2 to move up and down. A support plate 28 supporting the connecting block 27 is fixedly connected between the two corresponding positioning frames 22 on the left and right. The connecting block 27 is hinged between the support plate 28 and the support plate 21. The transmission component includes a guide plate 23 that drives the support plate 21 to move to the left. The connecting block 27 is set in an inclined position. By setting it in an inclined position, when the support plate 21 moves to the left, the connecting block 27 can be driven to rotate around the hinge point with the support plate 28 as the center. This allows the support plate 21 to move to the left while the connecting block 27 drives the roller 2 to move downward, so that the roller 2 is supported on the ground for easy movement.
[0031] Reference Figure 1 , Figure 2 and Figure 3 The top left side of the stabilizing block 210 is rotatably connected to a threaded rod 26 that drives the push plate 24 to move to the left. The top right side of the stabilizing block 210 is fixedly mounted with a servo motor 29 that drives the threaded rod 26 to rotate. The right side of the threaded rod 26 is fixedly connected to the left side of the output shaft of the servo motor 29. The bottom left side of the stabilizing block 210 is fixedly connected with a positioning plate 25 that increases the stability of the push plate 24's movement. The threaded part of the outer wall of the threaded rod 26 is threadedly connected to a push plate 24 that drives the guide plate 23 to move to the left. The push plate 24 passes through and is slidably connected to the outer wall of the positioning plate 25. When the guide plate 23 moves to the left, it also moves downwards. The push plate 24 vertically passes through the guide plate 23 and is slidably connected to the guide plate 23. The push plate 24, the positioning plate 25, the threaded rod 26, and the servo motor 29 constitute the drive assembly.
[0032] Reference Figure 1 , Figure 2 and Figure 3The right side of the support frame 1 is provided with a winding assembly for conveniently winding up the outwardly output hose. The winding assembly includes a winding roller 3, a fixing block 31, and a rotating rod 32. Two fixing blocks 31 are provided, both fixedly connected to the right side of the support frame 1. The rotating rod 32 is rotatably connected to the fixing block 31 and drives the winding roller 3. The winding roller 3 has a slot 33 to facilitate locking the hose for winding. One end of the rotating rod 32 is fixedly connected to a handwheel that drives the rotating rod 32 to rotate.
[0033] Working principle: When using this mobile fire pump, first start the servo motor 29. The output shaft of the servo motor 29 drives the threaded rod 26 to rotate. Since the push plate 24 is threadedly connected to the outer wall of the threaded rod 26, and the push plate 24 is slidably connected to the outer wall of the positioning plate 25, the push plate 24 will move to the left along the positioning plate 25 when the threaded rod 26 rotates. As the push plate 24 moves to the left, it will push the guide plate 23 to move to the left. The guide plate 23 is slidably connected to the outer wall of the push plate 24 and is also connected to the support plate 21. During the process of the guide plate 23 moving to the left, it will drive the support plate 21 to move to the left.
[0034] Because the connecting block 27 is set at an angle, its top end is hinged to the bottom of the second support plate 28, and its bottom end is hinged to the top of the first support plate 21. When the first support plate 21 moves to the left, the connecting block 27 will rotate around the hinge point with the second support plate 28, thereby pushing the first support plate 21 to move downward. The roller 2 is installed at the bottom of the first support plate 21, so the roller 2 will move downward and support the ground, realizing the moving function of the fire pump and facilitating the movement of the fire pump to the designated location.
[0035] When the fire pump reaches the working position and starts working, the servo motor 29 can be restarted to rotate in the reverse direction according to the ground conditions and the requirements for working stability, so that the roller 2 rises. At this time, the stabilizing block 210 contacts the ground to increase the contact area with the ground and increase the friction with the ground, thereby providing a stable support effect, preventing the fire pump from moving and causing the connecting pipe to fall off, thus ensuring a stable water supply effect.
[0036] When it is necessary to rewind the hose, flatten the hose and insert it into the slot 33. Then turn the handwheel, which drives the rotating rod 32 to rotate. The rotating rod 32 then drives the rewinding roller 3 to rotate. The rotation of the rewinding roller 3 quickly and orderly rewinds the hose, avoiding the tedious process of manual rewinding by firefighters, improving rewinding efficiency, and ensuring that fire equipment can be quickly organized after the operation is completed for the next use.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
