Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a remote water supply hose drainer. Background Technique

[0002] In the field of fire fighting, remote water supply hoses are mainly used for fire fighting and rescue operations at large fire scenes, mainly for supplying water to on-site fire fighting vehicles. Their laying distance can reach several kilometers, and the hoses have a large diameter and high hardness, such as large-caliber fire hoses with a diameter of 300 mm.

[0003] Remote water supply hoses are different from ordinary working hoses. Their long distance, large size, and high hardness make the drainage work before rewinding particularly difficult. The method of manually raising the hose for drainage requires a large amount of manpower, time, and energy, affecting the operation efficiency.

[0004] Therefore, based on long-term actual fire fighting operation experience, we designed and developed this remote water supply hose drainer. By placing the end of the hose on the water guide roller of the drainer and pushing the drainer forward, the residual water in the hose can be easily discharged. By applying it to fire fighting operations, good test results have been obtained. The drainage efficiency of the hose has been greatly improved, and a single person can complete the hose drainage work, improving the fire fighting operation efficiency. Content of the Utility Model

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 , this embodiment provides a remote water supply water hose drainer, including a main wheel shaft 1. Moving wheels 2 are arranged on both sides of the main wheel shaft 1. A water guiding roller 3 for lifting the water hose is arranged on the upper side of the main wheel shaft 1. A driving component for driving the water guiding roller 3 to rotate synchronously with the main wheel shaft 1 is arranged on the main wheel shaft 1. Specifically, the driving component includes two driving gears 4 symmetrically and fixedly sleeved on the main wheel shaft 1. Driven gears 5 are arranged on the outer walls on both sides of the water guiding roller 3. The driving gear 4 is meshed with the driven gear 5. When the main wheel shaft 1 rotates, the driven gear 5 and the water guiding roller 3 can be driven by the driving gear 4.

[0025] In order to realize the assembly of the water guiding roller 3, second bearing seats 8 located outside the driving gears 4 are symmetrically arranged on the main wheel shaft 1. A first bearing seat 7 is rotatably connected to the outside of the driven gear 5. The first bearing seat 7 and the second bearing seat 8 are fixedly connected by a first connecting rod 9. A push rod 6 is fixedly connected to the first bearing seat 7. By pushing the push rod 6, the driving of the main wheel shaft 1 can be realized. At the same time, by adjusting the push rod 6 up and down, the water guiding roller 3 can be adjusted in height along the circumference of the driving gear 4 with the movement of the push rod 6, improving the flexibility of the drainer. As Figure 1 shown, the push rod 6 is preferably a U-shaped rod, and the two end parts of the push rod 6 are respectively fixedly connected to the two first bearing seats 7, which is convenient for use.

[0026] In order to ensure the stability of the drainer during movement, two corresponding stable rear wheels 12 are arranged behind the moving wheels 2. The two stable rear wheels 12 are connected by an auxiliary wheel shaft 14. Two corresponding third bearing seats 10 are sleeved on the main wheel shaft 1. A fourth bearing seat 13 is rotatably connected to the outside of the stable rear wheel 12. The third bearing seat 10 and the fourth bearing seat 13 are fixedly connected by a second connecting rod 11.

[0027] It should be noted that the moving wheels 2, bearing seats, and stable rear wheels 12 are all conventional and general structures familiar to those skilled in the art, and can be obtained by custom purchase, so they will not be elaborated in this application. At the same time, as common knowledge familiar to those skilled in the art, in actual processing, it is preferably to design the driving gear 4 and the driven gear 5 as the same type of gears with the same size. At the same time, the diameter of the addendum circle of the driven gear 5 should be relative to the diameter of the water guide roller 3 to avoid the rotational speed of the driven gear 5 being too fast or too low relative to the forward speed of the drainer, resulting in excessive friction of the water guide roller 3 on the water belt 15 and affecting the quality of the water belt 15. The above design is common knowledge familiar to those skilled in the art during processing, and this application will not elaborate further.

[0028] When in use, as Figure 4 shown, place the water belt 15 for remote water guiding on the water guide roller 13, and push the drainer forward along the water belt 15. The water guide roller 13 rotates backward at the same time, making rolling contact with the water belt 15, reducing the friction on the water belt 15, and also facilitating the water guide roller 3 to continuously lift the water belt 15 forward, and the water in the water belt 15 can be easily pushed forward and discharged.

[0029] Embodiment 2

[0030] Please refer to Figures 5-6 , this embodiment provides a remote water supply water belt drainer. On the basis of Embodiment 1, the front-end structure of the drainer is further optimized. Since the remote water supply water belt has a high hardness, in actual application, simply pushing the water guide roller 3 forward can complete the drainage of the remote water supply water belt by one person, but firefighters still need a certain amount of force when pushing the drainer. Therefore, in order to better guide the water belt onto the water guide roller 3, a water belt front shovel plate 16 rotatably connected to the main wheel shaft 1 is provided on the front side of the main wheel shaft 1. The connection between the water belt front shovel plate 16 and the main wheel shaft 1 should be a conventional design familiar to those skilled in the art. Preferably, a rotating sleeve or bearing seat can be sleeved on the main wheel shaft 1, and the sleeve or bearing seat is fixedly connected to the main wheel shaft 1, which is a conventional design and will not be elaborated further in this application. At the same time, a plurality of guide wheels 17 are rotatably provided at the upper end of the water belt front shovel plate 16 to better realize the guiding effect on the water belt 15 and reduce the friction force of the surface of the water belt front shovel plate 16 on the water belt 15. In addition, front support wheels 18 are rotatably provided on both sides of the water belt front shovel plate 16 to realize the forward movement of the water belt front shovel plate 16.

[0031] In addition, in actual processing, as a conventional operation familiar to those skilled in the art, the inclination angle of the push handle 6 can be processed and designed according to actual needs, and this application will not limit it further. It can also be designed to be horizontal, as long as it is ensured that when pushing the drainer, the angle of the push handle 6 can facilitate the firefighters to exert force, and the water guide roller 3 can be located at a suitable water guiding position.

[0032] It should be noted that the above embodiments only describe the technical solutions and technical features of the present application specifically and clearly. For those skilled in the art, the solutions or features that belong to the prior art or common general knowledge are not described in detail in the above embodiments.

[0033] In addition, the technical solutions of the present application are not limited to the above embodiments. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
