Abstract
Description
Technical Field
[0001] This application relates to the field of fire hose technology, and in particular to a drain device for fire hoses. Background Technology
[0002] Fire hoses are indispensable equipment in firefighting, used to transport water from sources such as fire hydrants or fire trucks to the fire scene. They extinguish flames through water jets and cooling, preventing the fire from spreading. Many businesses (e.g., chemical plants) equip themselves with fire hoses as part of their internal fire protection systems to respond to sudden fires. After the firefighting process, some residual water remains in the fire hoses. If this residual water is not drained promptly, the prolonged retention of water inside the hose can cause the inner lining material to become damp and corroded, leading to adhesion and aging. This affects the lifespan of the fire hose and its usability in emergency firefighting situations. Furthermore, especially in cold northern regions, the residual water inside the fire hose may freeze, causing the hose to crack or be damaged.
[0003] However, after a fire is extinguished, most businesses and firefighters typically roll up the fire hoses and move them indoors to prevent the residual water from freezing and causing the hoses to crack or break, thus affecting their future use. This rolling and moving process is cumbersome, time-consuming, and labor-intensive. While the hoses won't freeze indoors, the residual water remaining inside for extended periods can still cause the hose's lining material to become damp and corrode. Therefore, this application proposes a residual water drainage device for fire hoses. Utility Model Content
[0004] This application provides a draining device for fire hoses to solve the technical problems described in the background section.
[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0006] This application provides a draining device for fire hoses, comprising:
[0007] Mounting base, the mounting base being used to connect to the reference surface;
[0008] A column is provided on the upper surface of the mounting base, and a bearing cylinder is provided on its top surface through a connecting plate;
[0009] A rotating shaft, one end of which passes through the bearing cylinder and is rotatably connected to the bearing cylinder, and a winding rod is provided at one end of which a fire hose is wound.
[0010] The first drain water assembly includes two vertical plates and two pressure hubs. The two vertical plates are disposed opposite each other on the upper surface of the mounting base and below the fire hose. The two pressure hubs are respectively mounted on the two vertical plates and are separated by a first preset gap. One end of the fire hose passes through the first preset gap.
[0011] Optionally, the unwinding rod includes a first unwinding rod, two second unwinding rods, and two third unwinding rods;
[0012] One end of the first unwinding rod is disposed at one end of the rotating shaft, and one end of each of the two second unwinding rods is disposed on the first unwinding rod, with both of them forming a preset angle with the first unwinding rod. The other ends of the two second unwinding rods are respectively connected to the third unwinding rod, which is parallel to the first unwinding rod.
[0013] Optionally, the preset included angle is 30°~60°.
[0014] Optionally, a friction layer is provided on the outer wall of the first unwinding rod, the two second unwinding rods, and the two third unwinding rods, and friction protrusions are provided on the friction layer.
[0015] Optionally, there are two columns, which are spaced apart along a first direction.
[0016] Optionally, the fire hose drain device further includes a second drain assembly with the same structure as the first drain assembly;
[0017] The distance between the two pressure hubs of the second drain assembly is a second preset gap, which is smaller than the first preset gap.
[0018] Optionally, a manual crank is provided at the other end of the rotating shaft.
[0019] Optionally, a drive motor is provided on the upper surface of the mounting base, and a drive gear is sleeved on the output shaft of the drive motor;
[0020] A driven gear is fitted on the shaft near its other end, and the driven gear is connected to the driving gear via chain drive.
[0021] Optionally, the mounting base is also provided with an emergency power supply module that is electrically connected to the drive motor.
[0022] The fire hose draining device provided in this application allows for the following process: after the fire hose has been used, workers squeeze out the water from within a predetermined length of the hose near one end (the predetermined length ensures that one end of the fire hose can be wound onto the unwinding rod, but the specific length depends on the actual situation and is not specifically limited in this application). The water is then forced through a first predetermined gap and wound onto the unwinding rod. The rotation of the rotating shaft drives the unwinding rod to rotate, continuously pulling the fire hose. During this continuous pulling, the fire hose is squeezed out of the remaining water through two pressure hubs. In other words, compared to existing methods of manually winding and carrying the fire hose indoors, this application not only achieves the goal of simultaneously squeezing out water and winding the fire hose, but also avoids the need to carry the fire hose indoors. Furthermore, the entire operation is time-saving and labor-saving, thereby improving the efficiency of squeezing out water and winding the fire hose. In addition, the mounting base makes the entire fire hose draining device easy to move, and the connection between the mounting base and the reference surface improves the stability of the entire fire hose draining device during the draining process.

Detailed Implementation
[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0032] refer to Figures 1 to 5 This application provides a draining device for fire hoses, comprising:
[0033] The mounting base 100 is used to connect to a reference surface. The reference surface can be the working surface of a factory building or the inner bottom surface of a fire truck compartment, depending on the location to be extinguished; therefore, this application does not specifically limit its application. Furthermore, the mounting base 100 can be connected to the reference surface by bolts or other means to improve the stability of the entire fire hose drainage device.
[0034] The column 200 is set on the upper surface of the mounting base 100, and the top surface of the column 200 is provided with a bearing cylinder 201 through the connecting plate 300; wherein, the connecting plate 300 is fixedly connected to the column 200, and the bearing cylinder 201 is fixedly connected to the connecting plate 300.
[0035] A rotating shaft 400 is provided, one end of which passes through the bearing cylinder 201 and is rotatably connected to the bearing cylinder 201. A winding rod 401 is provided at one end of the rotating shaft 400, on which a fire hose 500 is wound. The shaft of the rotating shaft 400 is rotatably connected to the inner circumferential wall of the bearing cylinder 201 through a bearing. The rotation of the rotating shaft 400 drives the rotation of the winding rod 401, and the winding rod 401 winds up and unwinds the fire hose 500 during the rotation process.
[0036] The first row of residual water assembly 600 includes two vertical plates 601 and two pressure hubs 602. The two vertical plates 601 are disposed opposite each other on the upper surface of the mounting base 100 and below the fire hose 500. The two pressure hubs 602 are respectively rotatably mounted on the two vertical plates 601, with a first preset gap between them. One end of the fire hose 500 passes through the first preset gap. The first preset gap is smaller than the thickness of the fire hose 500 when it contains residual water, and slightly larger than the thickness of the fire hose 500 when it does not contain residual water. This ensures that when the fire hose 500 passes through the first preset gap, the residual water inside can be squeezed out by the two pressure hubs 602, and that the fire hose 500 can smoothly pass through the first preset gap when unwinding after the residual water has been squeezed out, ensuring a smooth unwinding process. Therefore, the specific setting of the first preset gap can be determined according to actual needs, and this application does not specifically limit it. Since the two pressure hubs 602 are mounted on the two vertical plates 601 and rotate up and down, when one end of the fire hose 500 is fixed to the winding rod 401, the rotation of the winding rod 401 driven by the rotating shaft 400 causes the fire hose 500 to rotate in opposite directions during the continuous pulling process, thereby achieving the purpose of squeezing out the residual water in the fire hose 500 through the two pressure hubs 602.
[0037] The fire hose draining device provided in this application, after the fire hose 500 has been used, allows workers to squeeze out the water from the hose body near one end of a predetermined length (the predetermined length ensures that one end of the fire hose 500 can be wound onto the winding rod 401, depending on the actual situation, and this application does not specifically limit it) and force one end of the hose through the first predetermined gap, then wind one end of the fire hose 500 onto the winding rod 401. The rotation of the rotating shaft 400 then drives the winding rod 401. The rotating boom 401 continuously pulls the fire hose 500 during its rotation. As the fire hose 500 is continuously pulled, the two pressure hubs 602 squeeze out excess water. In other words, compared to existing methods of manually winding and carrying the fire hose indoors, this application not only achieves the goal of simultaneously squeezing water from the fire hose 500 and winding it up, but also avoids the need to carry the fire hose 500 indoors. Furthermore, the entire operation is time-saving and labor-saving, thus improving the efficiency of squeezing water from the fire hose 500 and winding it up. In addition, the mounting base 100 facilitates the movement of the entire fire hose drainage device, and the connection between the mounting base 100 and the reference surface improves the stability of the entire fire hose drainage device during the drainage process of the fire hose 500.
[0038] It should be noted that when it is necessary to use the fire hose 500 after the residual water has been drained, the rotation of the rotating shaft 400 drives the rotation of the unwinding rod 401. The rotation direction of the rotating shaft 400 is opposite to the winding direction of the fire hose 500, thereby realizing the unwinding of the fire hose 500 and facilitating its reuse.
[0039] In some embodiments, reference Figure 3 , Figure 5 and Figure 6 The unwinding rod 401 in this application includes a first unwinding rod 4011, two second unwinding rods 4012, and two third unwinding rods 4013. Specifically, one end of the first unwinding rod 4011 is disposed at one end of the rotating shaft 400, one end of each of the two second unwinding rods 4012 is disposed on the first unwinding rod 4011 and both of them form a preset angle with the first unwinding rod 4011, and the other ends of the two second unwinding rods 4012 are respectively connected to the third unwinding rods 4013 parallel to the first unwinding rod 4011.
[0040] In the above embodiment, since each second roll release rod 4012 forms a preset angle with the first roll release rod 4011, each third roll release rod 4013 is separated from the first roll release rod 4011 by a certain gap. The end of the fire hose 500 that discharges excess water passes through one of the gaps, and as the first roll release rod 4011, the second roll release rod 4012, and the third roll release rod 4013 rotate synchronously with the rotating shaft 400, the hose body of the fire hose 500 is sequentially wound around the third roll release rod 4013 corresponding to another gap, the first roll release rod 4011, and the third roll release rod 4013 corresponding to one of the gaps (see reference). Figure 6 This allows the fire hose 500 to be more securely fixed during the winding process, thereby improving the winding efficiency of the fire hose 500.
[0041] It is hereby specifically noted that the application provides Figure 1 , Figure 2 and Figure 6 The fire hose 500 shown is in its wound state. To prevent the fire hose 500 from scattering after winding, the end of the fire hose 500 that first discharges excess water is tied up. See [link / reference]. Figure 6 .
[0042] In some embodiments, reference Figure 3 The preset included angle in this application is 30°~60°.
[0043] In the above embodiments, if the preset angle is too small, the gap formed between the third unwinding rod 4013 and the first unwinding rod 4011 will be small, which may result in the fire hose 500 being unable to pass through the gap or the fire hose 500 being difficult to pull. Conversely, if the preset angle is too large, the gap formed between the third unwinding rod 4013 and the first unwinding rod 4011 will be large, which may result in the third unwinding rod 4013 and the first unwinding rod 4011 failing to clamp and fix the fire hose 500 when it passes through the gap, making it difficult to wind the fire hose 500. Therefore, the preset angle needs to be within a suitable range. A preset angle between 30° and 60° can be used for most specifications of fire hoses 500, so that the fire hose 500 can not only be clamped and fixed by the third reeling rod 4013 and the first reeling rod 4011, but also will not make the reeling rod 401 difficult to pull. The specific value of the preset angle can be set according to the specific specifications of the fire hose 500 to be drained and the specific specifications of the fire hose 500 to be rolled. This application does not make a specific limitation on it here.
[0044] In some embodiments, the outer walls of the first unwinding rod 4011, the two second unwinding rods 4012, and the two third unwinding rods 4013 in this application are all provided with a friction layer, and friction protrusions are provided on the friction layer. The number of friction protrusions and the spacing between each pair of adjacent friction protrusions can be set according to actual needs, and this application does not specifically limit them.
[0045] In the above embodiments, the friction layer and friction protrusions can be made of rubber, and can be specifically set according to actual needs, but this application does not specifically limit them. Specifically, the friction layer and friction protrusions are set to increase the friction between the third roll release rod 4013 and the first roll release rod 4011 and the fire hose 500, so that the fire hose 500 can be effectively clamped between the first roll release rod 4011 and the third roll release rod 4013. On the other hand, during the firefighting process, the fire hose 500 may have some impurities adhering to it due to the influence of the environment, and the friction protrusions can clean the outer surface of the fire hose 500.
[0046] In some embodiments, reference Figure 1 , Figure 2 , Figure 3 as well as Figure 5 This application includes two columns 200, which are spaced apart along a first direction. The spacing between the two columns 200 can be set according to actual conditions, and this application does not impose a specific limitation on it. Furthermore, since the rotating shaft 400 has a certain length, the arrangement of the two columns 200 can better support the rotating shaft 400, thereby ensuring the stability of the rotating shaft 400 during rotation.
[0047] In some embodiments, reference Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The fire hose drain device in this application also includes a second drain assembly 700 with the same structure as the first drain assembly 600; specifically, the distance between the two pressure hubs 602 of the second drain assembly 700 is a second preset gap, which is smaller than the first preset gap.
[0048] During the actual drainage of residual water from the fire hose 500 after use, the workers squeeze the water out of the hose body near one end of a predetermined length (where the predetermined length ensures that one end of the fire hose 500 can be wound onto the winding rod 401, depending on the actual situation, and this application does not specifically limit it) and cause one end of the hose to pass through the first and second predetermined gaps in sequence, and then wind one end of the fire hose 500 onto the winding rod 401 (see...). Figure 5 Since the second preset gap is smaller than the first preset gap, the setting of the first preset gap enables the primary drainage of the fire hose 500, while the setting of the second preset gap enables the secondary drainage of the fire hose 500, so that the residual water in the fire hose 500 is drained as cleanly as possible, thereby improving the discharge efficiency of the residual water in the fire hose 500.
[0049] In some embodiments, reference Figures 1 to 3 In this application, a manual crank 402 is provided at the other end of the rotating shaft 400. The rotating shaft 400 is rotated by the operator manually cranking the end of the crank 402 away from the rotating shaft 400.
[0050] In some embodiments, reference Figures 1 to 3 In this application, a drive motor 101 is provided on the upper surface of the mounting base 100, and a drive gear 1011 is sleeved on the output shaft of the drive motor 101. The model and specifications of the drive motor 101 can be set according to actual needs, and this application does not specifically limit them.
[0051] Specifically, a driven gear 403 is mounted on the shaft of the rotating shaft 400 near its other end, and the driven gear 403 is connected to the driving gear 1011 by a chain 800.
[0052] In the above embodiment, when the drive motor 101 is started, the output shaft of the drive motor 101 rotates, causing the drive gear 1011 mounted on it to rotate synchronously. Since the driven gear 403 is connected to the drive gear 1011 via a chain 800, the rotation of the drive gear 1011 drives the rotation of the driven gear 403, which is connected to it via a chain 800. Since the driven gear 403 is mounted on the rotating shaft 400, the rotating shaft 400 and the driven gear 403 rotate synchronously, thereby realizing the electric drive of the rotating shaft 400 and improving the rotation efficiency of the rotating shaft 400.
[0053] In some embodiments, reference Figures 1 to 3 The mounting base 100 in this application is also equipped with an emergency power module 102 that is electrically connected to the drive motor 101. Since the drive motor 101 is typically started by connecting to an external power source, there may be situations outdoors where connecting to a power source is inconvenient. The emergency power module 102 can supply power to the drive motor 101 when it is inconvenient to connect to a power source outdoors, ensuring the normal operation of the drive motor 101. The emergency power module 102 can be a lithium battery module, a lithium iron phosphate battery module, or a solar photovoltaic module, etc., and can be specifically configured according to actual needs; this application does not impose any specific limitations on it.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
