Description

Technical Field

[0001] This application belongs to the field of emergency equipment technology, specifically relating to a fire hose retrieval method, a fire hose retrieval system, emergency equipment, and a machine-readable storage medium. Background Technology

[0002] In order to achieve long-distance water supply, existing fire trucks with hose laying require hoses with a length greater than 1km, and are generally configured with 2 to 3km. In order to meet the hose length requirement, the hose needs to be made up of multiple 100m hose sections connected by joints.

[0003] When it is necessary to recycle the hoses into the hose box, the current recycling devices on fire trucks are not intelligent enough, so manual assistance is still required to organize the hoses inside the hose box. This is to ensure that the hoses are stacked neatly and to reduce clutter. However, this process is time-consuming and labor-intensive. Furthermore, due to human intervention, the method of neatly stacking the hoses cannot be standardized, and a certain degree of randomness is introduced, making it difficult to effectively improve the utilization rate of the internal space of the hose box. Summary of the Invention

[0004] The purpose of this application is to provide a method and system for fire hose retrieval, emergency equipment, and a machine-readable storage medium, which can improve the intelligence level of hose retrieval, optimize and standardize the hose stacking method, thereby saving labor intensity, improving hose retrieval efficiency, and increasing the space utilization of the hose storage compartment.

[0005] To achieve the above objectives, this application provides a method for retrieving fire hoses, comprising:

[0006] The water hose is conveyed from front to back to the drop-off port at the top rear of the storage tank at a first speed V1 using a conveying device, so that the water hose can fall from the drop-off port into the storage tank at the first speed V1.

[0007] When the hose joint does not enter the conveying device and the hose stacking height in the storage box is not higher than the preset height H, the hose handling device repeatedly and alternately performs the clamping and pulling action and the backward empty walking action at the first speed V1 within the preset forward and backward stroke L0 at the inner top of the storage box, so that each hose segment with a length of L1 is folded and stacked in the storage box, where L1 = 2L0;

[0008] When the connector enters the conveying device and the water hose stacking height in the storage box is not higher than the preset height H, the movement state of the belt guide device is adjusted according to the moving direction of the belt guide device and the front-to-back distance S between the belt guide device and the connector, so that the connector falls from the drop port into the rear of the storage box.

[0009] In some embodiments, adjusting the movement state of the tape-tipping device according to its moving direction and the front-to-back distance S between the tape-tipping device and the connector includes:

[0010] When L > 2L0, the connector enters the front end of the conveying device, and the belt feeding device performs the belt pulling action, the belt feeding device is first allowed to continue to perform the belt pulling action within the current preset forward and backward stroke L0 at the first speed V1, where L is the total conveying length of the conveying device;

[0011] When the tape feeding device has completed the current tape pulling action and S > L0 / 2, calculate the length L2 of the second water hose segment extending from the joint to the tape drop outlet;

[0012] The conveyor belt device accelerates relative to the first speed V1 during the backward empty-walking action to clamp the second water hose segment at half its length at the drop-off point.

[0013] The tape handling device performs the tape pulling action and the backward empty walking action sequentially within the first correction stroke L0' at the first speed V1, so that the second water tape segment can be folded and stacked below the preset height H in the tape storage box, where L2 = 2L0'.

[0014] In some embodiments, adjusting the movement state of the tape-tipping device according to its moving direction and the front-to-back distance S between the tape-tipping device and the connector includes:

[0015] When the conveying device delivers the connector to the front top of the storage box, the tape handling device performs the backward empty-walking action and S>L0 / 2, calculate the length L3 of the third water hose segment extending from the connector to the water hose stack at the rear bottom of the storage box;

[0016] The conveyor belt device accelerates relative to the first speed V1 while continuing to perform the current backward walking motion to clamp the third water hose segment at half its length at the drop outlet.

[0017] The tape handling device performs the tape-pulling action and the backward empty-walking action sequentially within the second correction stroke L0” at the first speed V1, so that the third water tape segment can be folded and stacked below the preset height H in the tape storage box, where L3 = 2L0”.

[0018] In some embodiments, adjusting the movement state of the tape-tipping device according to its moving direction and the front-to-back distance S between the tape-tipping device and the connector includes:

[0019] When the conveying device delivers the connector to the front top of the storage box, and the tape handling device performs the backward empty-running action and S≤L0 / 2, the tape handling device is stopped from performing the current backward empty-running action or the tape handling device is not performed from performing the clamping and pulling action after completing the current backward empty-running action.

[0020] In some embodiments, the fire hose retrieval method further includes:

[0021] The water hose is stacked in multiple storage spaces using the aforementioned hose sorting device, and the water hose in each storage space is stacked to the preset height H. The multiple storage spaces are formed sequentially in the left-right direction within the storage compartment.

[0022] With the water hoses in each of the storage spaces stacked to the preset height H, the hose handling device moves back and forth synchronously while repeatedly performing the clamping and pulling action and the backward walking action.

[0023] In some embodiments, the fire hose retrieval method further includes:

[0024] When all the water hoses in each of the storage spaces are stacked to the preset height H and the hose handling device continues to perform the backward empty walking action, when it is determined that the hose handling device and the connector can reach the drop port at the same time, the hose handling device will not perform the clamping and pulling action after completing the current backward empty walking action.

[0025] A second aspect of this application also provides a fire hose recovery system, comprising:

[0026] A tape storage compartment, wherein a tape drop-off port is provided at the rear top of the tape storage compartment;

[0027] A conveying device for conveying the water hose from front to back to the hose drop-off port;

[0028] The belt handling device is movable back and forth at the bottom of the conveyor and can clamp or release the water belt at the top inside the belt storage compartment;

[0029] A left-right moving device for driving the conveying device to move left and right; and

[0030] The monitoring assembly is capable of performing the above-described fire hose retrieval method by monitoring the hose, the conveying device, the hose handling device, and the left and right moving device.

[0031] In some embodiments, the monitoring assembly includes:

[0032] A first sensor is used to detect whether the connector enters the front end of the conveying device;

[0033] The second sensor is used to detect whether the connector is conveyed to the front top of the storage box by the conveying device;

[0034] A first position sensor is used to detect whether the connector has passed through the tape dropper.

[0035] The second position sensor is used to detect the front and rear positions of the tape feeding device;

[0036] A third position sensor is used to detect the left and right positions of the conveying device;

[0037] A height sensor is used to detect the stacking height of the water hoses in the storage compartment; and

[0038] The processor communicates with the first sensor, the second sensor, the first position sensor, the second position sensor, the third position sensor, the height sensor, the conveying device, the belt handling device, and the left and right moving device.

[0039] In some embodiments, the conveying device includes a guide belt device and a take-up belt device connected front and rear. The take-up belt device extends from the front top of the storage box to the drop-off port. The front end of the take-up belt device is provided with an openable front pressing mechanism, and the rear end of the take-up belt device is provided with an openable rear pressing mechanism.

[0040] In some embodiments, the conveying device includes a guide belt device and a take-up belt device connected front to back, the take-up belt device extending from the front top of the storage compartment to the drop-off port, the guide belt device being telescopic, and the monitoring assembly including a length sensor for detecting the front-to-back length of the guide belt device.

[0041] A third aspect of this application also provides an emergency device that includes the aforementioned fire hose recovery system.

[0042] A fourth aspect of this application also provides a machine-readable storage medium storing instructions that cause a machine to perform the above-described fire hose retrieval method.

[0043] By adopting the fire hose recovery technology of this application, when the hose enters the conveying device without joints and the stacking height of the hose in the storage box is not higher than the preset height H, both the hose handling device and the conveying device move at a first speed V1. Whenever the length of the hose falling from the drop port into the rear of the storage box reaches L1 / 2, the hose handling device can clamp the hose at the drop port (equivalent to clamping half the length of the first hose segment with a clamping length of L1), and then move forward, performing a clamping and pulling action within a preset forward and backward stroke L0 (equal to L1 / 2). At the same time, the conveying device continues to convey the hose at the first speed V1. When the hose handling device has traveled the preset forward and backward stroke L0, the hose handling device immediately releases the hose, so that the first hose segment can be folded in half and stacked in the storage box. Then, the belt feeding device moves in the opposite direction and performs a backward empty movement within the preset forward and backward travel L0. Similarly, the conveying device continues to convey the water belt at the first speed V1. When the belt feeding device reaches the drop outlet after traveling the preset forward and backward travel L0, the length of the water belt falling from the drop outlet into the rear of the storage box reaches L1 / 2 again. In this way, the belt feeding device can once again perform a clamping and pulling action within the preset forward and backward travel L0 to fold and stack a new first water belt segment.

[0044] When a joint enters the conveying device and the height of the hose stacked in the storage compartment is not higher than the preset height H, the fire hose retrieval technology of this application can adjust the movement state of the hose handling device (such as speed change, not performing clamping action, etc.) according to the moving direction of the hose handling device and the front-to-back distance S between the hose handling device and the joint. This adjusts the timing of the hose handling device clamping the hose and the travel range of the hose handling device when performing the clamping and pulling action and the backward walking action, so that the joint can finally fall from the hose drop port into the rear of the storage compartment for stacking.

[0045] Therefore, this application can adopt different hose recovery strategies based on whether there are joints entering the conveying device, and automatically execute different strategies through the coordinated cooperation of the conveying device and the hose sorting device. This can improve the intelligence level of hose recovery, optimize and unify the stacking method of hoses and their joints, thereby saving labor intensity, improving hose recovery efficiency and space utilization of the hose storage box.

[0065] Reference Figures 1 to 3 The first exemplary embodiment of this application provides a method for retrieving a fire hose, which includes:

[0066] The conveying device 20 conveys the water hose 100 from front to back to the drop port 101 at the top rear of the storage tank 10 at a first speed V1, so that the water hose 100 can fall from the drop port 101 into the storage tank 10 at a first speed V1.

[0067] When the joint 110 of the water hose 100 has not entered the conveying device 20 and the stacking height of the water hose in the storage box 10 is not higher than the preset height H, the belt handling device 30 repeatedly and alternately performs the clamping and pulling action and the backward empty walking action at the inner top of the storage box 10 at the first speed V1 within the preset forward and backward stroke L0, so that the first water hose segment with a length of L1 is folded and stacked in the storage box 10, where L1 = 2L0;

[0068] When the connector 110 enters the conveying device 20 and the water hose stacking height in the storage box 10 is not higher than the preset height H, the movement state of the belt guide device 30 is adjusted according to the moving direction of the belt guide device 30 and the front-to-back distance S between the belt guide device 30 and the connector 110, so that the connector 110 falls from the drop port 101 into the rear of the storage box 10.

[0069] It should be noted that the belt feeding device 30 can switch between an open state and a closed state. The belt feeding device 30 can be switched to a closed state to clamp the water hose, or it can be switched to an open state to release the water hose. The mechanism in the belt feeding device 30 for clamping or releasing the water hose is prior art and will not be described in detail here. Similarly, the conveying device can adopt different forms such as roller conveyors, which are also prior art and will not be described in detail here.

[0070] Furthermore, the first water hose segment with a length of L1 does not specifically refer to a water hose segment at a certain location in the conveyor 20 or the storage compartment 10, but rather to a water hose segment that can be folded and stacked within a length range that is equal to the preset forward and backward travel L0.

[0071] More specifically, when the belt feeding device 30 is at the very front of its preset forward and backward travel L0, the front end of the first water hose segment (hereinafter referred to as the first end) is on the conveying device 20 and the rear end (hereinafter referred to as the second end) just passes through the drop-off port 101; immediately afterward, the belt feeding device 30 begins to move backward at a first speed V1, while the conveying device 20 continuously conveys the water hose 100 at the first speed V1; when the belt feeding device 30 moves to the very rear of its preset forward and backward travel L0 (i.e., just passes through the drop-off port 101), the second end of the first water hose segment has fallen into the storage tank 10. The first water hose segment is stacked and stuck at the rear bottom of the storage compartment 10, and its half-length position (i.e., the middle position) is just passing through the drop outlet 101 and can be clamped by the hose handling device 30. Then, the hose handling device 30 moves forward while clamping the half-length position of the first water hose segment, performing a clamping and pulling action. This gradually straightens the portion of the first water hose segment stacked and stuck at the rear bottom of the storage compartment 10 diagonally upwards and forwards, while the conveying device 20 continuously conveys the water hose 100 at the first speed V1. When the hose handling device 30 reaches the front end of its preset forward and backward stroke L0 (refer to...), Figure 2 When the first end of the first water hose segment passes through the drop outlet 101, if the belt handling device 30 releases the water hose and starts to move backward, the first water hose segment can gradually fall down as the conveying device 20 always conveys the water hose 100 at the first speed V1 during the backward movement of the belt handling device 30. When the belt handling device 30 reaches the end of its preset forward and backward travel L0 again, the first water hose segment is folded in half and stacked in the belt storage box 10.

[0072] Therefore, if the belt feeding device 30 repeatedly performs the clamping and pulling action and the backward empty walking action at the top of the belt storage box 10 at a first speed V1 within a preset forward and backward stroke L0, and the conveying device 20 keeps conveying the water belt 100 at the first speed V1, then each first water belt segment of length L1 can be folded and stacked in the belt storage box 10. If the left and right positions of the belt feeding device 30 do not change, the next first water belt segment can be stacked on the previous first water belt segment, thus gradually stacking higher until the water belt stacking height reaches the preset height H.

[0073] By adopting the above method, when the seamless 110 enters the conveying device 20 and the water hose stacking height in the storage box 10 is not higher than the preset height H, both the belt handling device 30 and the conveying device 20 move at the first speed V1. Whenever the length of the water hose 100 falling from the drop port 101 into the rear of the storage box 10 reaches L1 / 2, the belt handling device 30 can clamp the water hose 100 at the drop port 101 (equivalent to the position of clamping half the length of the first water hose segment with a clamping length of L1), and then move forward to perform the clamping and pulling action within the preset forward and backward stroke L0 (equal to L1 / 2). At the same time, the conveying device 20 still maintains the conveying of the water hose 100 at the first speed V1. When the belt handling device 30 has gone through the preset forward and backward stroke L0, the belt handling device 30 immediately releases the water hose, so that the first water hose segment can be folded in half and stacked in the storage box. Then, the belt feeding device 30 moves in the opposite direction and performs a backward empty movement within the preset forward and backward travel L0. Similarly, the conveying device 20 continues to convey the water belt 100 at the first speed V1. When the belt feeding device 30 reaches the drop outlet 101 after traveling the preset forward and backward travel L0, the length of the water belt falling from the drop outlet 101 into the rear of the storage box 10 reaches L1 / 2 again. In this way, the belt feeding device 30 can once again perform a clamping and pulling action within the preset forward and backward travel L0 to fold and stack a new first water belt segment.

[0074] When a connector 110 enters the conveying device 20 and the water hose stacking height in the storage box 10 is not higher than the preset height H, this application can adjust the movement state of the belt guide device 30 (such as speed change, not performing clamping action, etc.) according to the moving direction of the belt guide device 30 and the front-to-back distance S between the belt guide device 30 and the connector 110. This adjusts the timing of the belt guide device 30 clamping the water hose and the travel range of the belt guide device 30 when performing the clamping and pulling action and the backward empty walking action, so that the connector 110 can finally fall from the drop port 101 into the rear bottom of the storage box 10 for stacking. In this way, when the water hose stacking height is not higher than the preset height H, it can be ensured that each connector 110 is stacked at the rear bottom of the storage box 10, making the placement of the connector 110 more regular and orderly when it is not higher than the preset height H.

[0075] Therefore, this application can adopt different hose recovery strategies depending on whether the hose connector 110 enters the conveying device 20. Through the coordinated cooperation of the conveying device 20 and the hose handling device 30, different strategies can be automatically executed, which can improve the intelligence level of hose recovery and optimize and unify the stacking method of hose 100 and its connector 110. This can save labor intensity, improve hose recovery efficiency and space utilization of the hose storage box 10.

[0076] In some embodiments, a bottom recess 102 is formed at the rear bottom of the tape storage compartment 10. This bottom recess 102 is typically provided at the rear bottom of the tape storage compartment 10 to facilitate access for workers when they need to retrieve the hose 100 or manually assist in stacking the hose inside the compartment. In this application, by employing the method described above, the bottom recess 102 can be used to stack the connector 110, thereby making fuller use of the internal space of the tape storage compartment 10. Furthermore, the depth of the bottom recess 102 can be set to be approximately the same as the height of the connector 110. Thus, when the connector 110 is placed in the bottom recess 102, such as the first water hose segment mentioned above, water hose segments without connectors can be placed relatively flat in the storage box 10 because their rear is supported by the connector 110, and they will not fall into the bottom recess 102. As a result, the stacked shape is more regular, further optimizing the stacking method for water hose segments without connectors.

[0077] In some embodiments, adjusting the movement state of the tape feeding device 30 according to the moving direction of the tape feeding device 30 and the front-to-back distance S between the tape feeding device 30 and the connector 110 includes:

[0078] When L > 2L0, the connector 110 enters the front end of the conveyor 20 and the belt feeding device 30 performs a clamping and pulling action, the belt feeding device 30 is first made to continue to perform the clamping and pulling action within the current preset forward and backward stroke L0 at the first speed V1, where L is the total conveying length of the conveyor 20.

[0079] When the tape handling device 30 has completed the current tape pulling action and S > L0 / 2, calculate the length L2 of the second water hose section extending from the joint 110 to the tape drop outlet 101.

[0080] When the conveyor belt device 30 performs a backward empty movement, it accelerates relative to the first speed V1 (for example, it first accelerates at the second speed V2 and then decelerates to the first speed V1) to clamp the second water hose segment at half its length at the tape drop outlet 101.

[0081] The conveyor belt device 30 performs a clamping and pulling action and a backward empty walking action in sequence within the first correction stroke L0' at a first speed V1, so that the second water hose section can be folded and stacked below the preset height H in the storage box 10, where L2 = 2L0'.

[0082] It should be noted that when L > 2L0, the connector 110 enters the front end of the conveyor 20 and the belt guide device 30 performs the clamping and pulling action, it is certain that since the conveyor 20 maintains the conveying of the water belt 100 at the first speed V1, if the belt guide device 30 still performs the clamping and pulling action within the preset forward and backward stroke L0 at the first speed V1 and is at the front end of the preset forward and backward stroke L0, then the distance between the connector 110 and the drop outlet 101 is still greater than L0 (and usually less than 2L0). The water belt segment between the connector 110 and the drop outlet 101 at this moment is defined as the second water belt segment, which is equivalent to the length L2 of the second water belt segment being greater than L0 (and usually less than 2L0).

[0083] If the length L2 of the second water hose section is greater than L0 and less than 2L0, and the hose handling device 30 continues to move backward at the first speed V1 from the front end of the preset forward and backward stroke L0, then before the hose handling device 30 reaches the drop outlet 101, the half-length position (i.e., the middle position) of the second water hose section will have reached the drop outlet 101. Therefore, when the hose handling device 30 reaches the drop outlet 101, it cannot clamp the half-length position of the second water hose section, and thus the connector 110 cannot be vertically lowered from the drop outlet 101 to the rear bottom of the storage box 10.

[0084] Therefore, if the belt feeding device 30 starts moving backward from the front end of the preset forward and backward stroke L0, it needs to move at a speed greater than the first speed V1 to have a chance to clamp the second water hose segment at the half-length position. However, at this time, the size of the forward and backward distance S between the belt feeding device 30 and the connector 110 also needs to be considered to determine whether the belt feeding device 30 can catch up with the second water hose segment at the half-length position if it speeds up. Specifically, when the front-to-back distance S is large, it means that the distance between the connector 110 and the tape dropper 101 is still relatively far (e.g., L2 is close to 2L0). Therefore, by increasing the speed of the tape handling device 30, the tape handling device 30 can catch up with the half-length position of the second water hose segment and thus clamp the half-length position at the tape dropper 101. However, when the front-to-back distance S is small, it means that the distance between the connector 110 and the tape dropper 101 is small (e.g., L2 is only slightly greater than L0). At this time, even if the speed of the tape handling device 30 is increased, the tape handling device 30 cannot catch up with the half-length position of the second water hose segment and thus cannot clamp the half-length position at the tape dropper 101.

[0085] This embodiment, based on practical considerations, uses L0 / 2 as the dividing point between larger and smaller front-to-back distances S. Specifically, when S > L0 / 2, it is determined that by increasing the speed of the conveyor belt loader 30, it can catch up with the half-length position of the second water hose segment. At this point, the specific value of the water hose segment length L2 of the second water hose segment can be calculated to determine the half-length position of the second water hose segment, thereby further determining the speed increase of the conveyor belt loader 30 so that it can clamp the half-length position when it moves to the tape dropper 101.

[0086] Furthermore, when the belt guide device 30 clamps the second hose segment at half its length and performs the clamping and pulling action, the travel range of the belt guide device 30 needs to be adjusted to ensure that when the connector 110 reaches the hose drop outlet 101, the belt guide device 30 just releases the hose and begins to move backward. Therefore, in this embodiment, when the belt guide device 30 clamps the second hose segment at half its length and sequentially performs the clamping and pulling action and the backward movement, its travel range needs to be adjusted to the first corrected forward and backward travel range L0', and L2 = 2L0'. Additionally, when the belt guide device 30 clamps the second hose segment at half its length and sequentially performs the clamping and pulling action and the backward movement, it can return to moving at the first speed V1.

[0087] The following are some alternative embodiments in which the steps of this embodiment can be performed:

[0088] In one optional embodiment, a first sensor 40 detects whether the connector 110 enters the front end of the conveyor 20, a second position sensor 70 detects the front and rear positions of the belt handling device 30, and a height sensor 80 detects the stacking height of the water hose 100 in the storage compartment 10. A processor 90 communicates with the first sensor 40, the second position sensor 70, the height sensor 80, the conveyor 20, and the belt handling device 30. The processor 90 has a pre-stored calculation and analysis program. Furthermore, the total conveying length L of the conveyor 20 is constant and satisfies L > 2L0, and L is pre-stored in the processor 90. A preset height H is also pre-stored in the processor 90.

[0089] When the processor 90 determines that the height of the water hose stacked in the storage compartment 10 is not higher than the preset height H, and when the first sensor 40 detects that the connector 110 has entered the front end of the conveyor 20 and the processor 90 determines that the belt feeding device 30 is performing a clamping and pulling action, the processor 90 first controls the belt feeding device 30 to continue performing the clamping and pulling action within the preset forward and backward stroke L0 at the first speed V1. During this process, the processor 90 can obtain the moving distance of the belt feeding device 30 through the second position sensor 70. This moving distance of the belt feeding device 30 is equal to the moving distance of the synchronously moving connector 110. Therefore, when the belt feeding device 30 completes the current clamping and pulling action, the position of the connector 110 can be determined, and the position of the belt feeding device 30 can be obtained by the second position sensor 70. Therefore, the processor 90 can calculate the forward and backward distance S between the belt feeding device 30 and the connector 110, and further determine the relationship between S and L0 / 2.

[0090] If S > L0 / 2, the processor 90 can calculate the difference between the total conveying length L and the moving distance of the connector 110 to obtain the specific value of the length L2 of the second hose segment extending from the connector 110 to the hose drop outlet 101, thereby determining the half-length position of the second hose segment. Furthermore, with the specific value of the hose segment length L2 determined, the travel L0' before and after the first correction can be determined based on L2 = 2L0'.

[0091] Then, the processor 90 automatically calculates the acceleration of the tape feeding device 30 through its calculation and analysis program, ensuring that the tape feeding device 30 accelerates relative to the first speed V1 when performing the backward empty movement (for example, first accelerates at the second speed V2, and then decelerates to the first speed V1) so as to clamp the second water tape segment at half the length position at the tape drop outlet 101.

[0092] When the tape feeding device 30 has clamped the second water hose segment at half its length position in the tape dropper 101, the tape feeding device 30 performs a clamping and pulling action and a backward empty walking action in sequence within the first correction stroke L0' at a first speed V1, so that the second water hose segment can be folded and stacked below the preset height H in the tape storage box 10.

[0093] In another optional embodiment, the conveying device 20 includes a guide belt device 201 and a take-up belt device 202 connected front to back. The take-up belt device 202 extends from the front top of the storage box 10 to the drop-off port 101, and the guide belt device 201 is telescopic. Therefore, the front-to-back length of the take-up belt device 202 is known and constant, while the front-to-back length of the guide belt device 201 is variable. The total conveying length L of the conveying device 20 is the sum of the front-to-back lengths of the take-up belt device 202 and the guide belt device 201, and L is also variable. Furthermore, in this optional embodiment, a length sensor is provided to detect the front-to-back length of the guide belt device 201, and this length sensor communicates with the processor 90. By pre-storing the front-to-back length of the take-up belt device 202 in the processor 90, and by obtaining the front-to-back length of the guide belt device 201 from the length sensor in real time, the processor 90 can automatically calculate the total conveying length L of the conveying device 20.

[0094] As can be seen, the only difference between the two optional embodiments is the method of determining the total conveying length L. All other settings are the same. Both optional embodiments can achieve the folding and stacking of the second water hose section, while ensuring that the joint 110 falls vertically to the rear bottom of the storage box 10.

[0095] In some embodiments, adjusting the movement state of the tape feeding device 30 according to the moving direction of the tape feeding device 30 and the front-to-back distance S between the tape feeding device 30 and the connector 110 includes:

[0096] When the conveying device 20 conveys the connector 110 to the front top of the storage box 10, the belt handling device 30 performs a backward empty movement and S>L0 / 2, calculate the length L3 of the third water hose segment extending from the connector 110 to the water hose stack at the rear bottom of the storage box 10.

[0097] The conveyor belt device 30 accelerates relative to the first speed V1 while continuing to perform the current backward empty movement (for example, it first accelerates at the second speed V2 and then decelerates to the first speed V1) to clamp the third water hose segment at half its length position at the tape drop outlet 101.

[0098] The conveyor belt device 30 performs a clamping and pulling action and a backward emptying action in sequence within the second correction stroke L0” at a first speed V1, so that the third water hose section can be folded and stacked below the preset height H in the storage box 10, where L3 = 2L0”.

[0099] It should be noted that when the conveyor 20 conveys the connector 110 to the front top of the storage box 10, the belt handling device 30 is performing a backward empty movement and S > L0 / 2, the section of water hose extending from the connector 110 to the water hose stack at the rear bottom of the storage box 10 is defined as the aforementioned third water hose section, and the length of this third water hose section is L3. Since S > L0 / 2, it means that the distance between the belt handling device 30 and the drop outlet 101 is no greater than L0 / 2. Therefore, by increasing the speed of the belt handling device 30, the belt handling device 30 can catch up with the half-length position of the third water hose section, thereby clamping the half-length position at the drop outlet 101.

[0100] Furthermore, when the belt guide device 30 clamps the third hose segment at half its length and performs the clamping and pulling action, the travel range of the belt guide device 30 needs to be adjusted to ensure that when the connector 110 reaches the hose drop outlet 101, the belt guide device 30 just releases the hose and begins to move backward. Therefore, in this embodiment, when the belt guide device 30 clamps the third hose segment at half its length and sequentially performs the clamping and pulling action and the backward movement, its travel range needs to be adjusted to the second corrected forward and backward travel range L0", and L3 = 2L0". Additionally, when the belt guide device 30 clamps the third hose segment at half its length and sequentially performs the clamping and pulling action and the backward movement, it can return to moving at the first speed V1.

[0101] The following examples illustrate alternative embodiments in which the steps in this embodiment can be performed:

[0102] In one optional embodiment, a second sensor 50 detects whether the connector 110 has been conveyed to the front top of the storage compartment 10 by the conveying device 20, a second position sensor 70 detects the front and rear positions of the strapping device 30, and a height sensor 80 detects the stacking height of the water hose 100 in the storage compartment 10. A processor 90 communicates with the second sensor 50, the second position sensor 70, the height sensor 80, the conveying device 20, and the strapping device 30. The processor 90 contains a pre-stored calculation and analysis program. A preset height H is also pre-stored in the processor 90.

[0103] When the processor 90 determines that the height of the water hose stacking in the storage compartment 10 is not higher than the preset height H, when the second sensor 50 detects that the connector 110 is conveyed to the front top of the storage compartment 10 by the conveying device 20, the processor 90 determines that the hose handling device 30 is performing a backward empty walking action, and the processor 90 determines the front-back distance S determined by the front-back position of the connector 110 (located at the front top of the storage compartment 10, the position of which is known) and the front-back position of the hose handling device 30 obtained from the second position sensor 70, which satisfies S > L0 / 2, the processor 90 first calculates the length L3 of the third water hose segment extending from the connector 110 to the water hose stacking at the rear bottom of the storage compartment 10.

[0104] It is known that when the connector 110 is at the front top of the tape storage box 10, the front-to-back distance between the connector 110 and the tape drop outlet 101 is equal to the front-to-back distance between the front top of the tape storage box 10 and the tape drop outlet 101. The front-to-back distance between the front top of the tape storage box 10 and the tape drop outlet 101 is a known quantity determined by the structure of the tape storage box 10. Therefore, the front-to-back distance between the connector 110 and the tape drop outlet 101 (i.e., equal to the length of the water hose section between the connector 110 and the tape drop outlet 101) can be pre-stored in the processor 90 as a known quantity. As for the length of the water hose segment extending from the drop outlet 101 to the water hose stack at the bottom of the storage box 10, it is actually equivalent to the front-to-back distance between the current tape handling device 30 and the front end of the preset front-to-back L0. Therefore, the processor 90 only needs to obtain the front-to-back distance traveled by the tape handling device 30 from the front end of the preset front-to-back L0 to the current position through the second position sensor 70, which is equivalent to obtaining the length of the water hose segment extending from the drop outlet 101 to the water hose stack at the bottom of the storage box 10.

[0105] Therefore, having determined the length of the hose section between the connector 110 and the drop outlet 101, and the length of the hose section extending from the drop outlet 101 to the bottom of the hose stack in the storage compartment 10, summing the two yields the specific value of the hose section length L3 for the third hose section, thus determining the half-length position of the third hose section. Furthermore, with the specific value of the hose section length L3 determined, the second correction stroke L0 can be determined based on L3 = 2L0".

[0106] Then, the processor 90 automatically calculates the acceleration of the tape feeding device 30 through its calculation and analysis program, ensuring that the tape feeding device 30 accelerates relative to the first speed V1 when performing the backward empty movement (for example, first accelerates at the second speed V2, and then decelerates to the first speed V1) so as to clamp the third water tape segment at half the length position at the tape drop outlet 101.

[0107] When the belt feeding device 30 has clamped the third water hose section at half its length position in the belt drop outlet 101, the belt feeding device 30 performs the clamping and pulling action and the backward empty walking action in sequence at the first speed V1 within the second correction stroke L0”, so that the third water hose section can be folded and stacked below the preset height H in the belt storage box 10.

[0108] In some embodiments, adjusting the movement state of the tape feeding device 30 according to the moving direction of the tape feeding device 30 and the front-to-back distance S between the tape feeding device 30 and the connector 110 includes:

[0109] When the conveyor 20 conveys the connector 110 to the front top of the storage box 10, and the belt handling device 30 performs a backward empty movement and S≤L0 / 2, the belt handling device 30 is stopped from performing the current backward empty movement or the belt handling device 30 is not performed from the clamping and pulling action after completing the current backward empty movement.

[0110] It should be noted that when the conveying device 20 delivers the connector 110 to the front top of the storage box 10, and the belt handling device 30 is performing a backward empty movement and S≤L0 / 2, since S≤L0 / 2 means that the distance between the belt handling device 30 and the belt drop outlet 101 is greater than L0 / 2, even if the belt handling device 30 is accelerated, the belt handling device 30 still cannot catch up with the half-length position of the third water hose section, and thus cannot clamp the half-length position at the belt drop outlet 101.

[0111] Therefore, in this embodiment, the tape feeding device 30 can be stopped from performing the current backward empty movement, or the tape feeding device 30 can be prevented from performing the tape clamping and pulling movement after completing the current backward empty movement, so that the connector 110 can fall vertically from the tape drop outlet 101 to the rear bottom of the tape storage box 10. The situation described in this embodiment generally only occurs when the last section of water hose is being retrieved.

[0112] The following examples illustrate alternative embodiments in which the steps in this embodiment can be performed:

[0113] In one optional embodiment, a second sensor 50 detects whether the connector 110 has been conveyed to the front top of the storage compartment 10 by the conveying device 20, a first position sensor 60 detects whether the connector 110 has passed through the tape drop port 101, a second position sensor 70 detects the front and rear positions of the tape handling device 30, and a height sensor 80 detects the stacking height of the water hose 100 in the storage compartment 10. A processor 90 is provided to communicate with the second sensor 50, the first position sensor 60, the second position sensor 70, the height sensor 80, the conveying device 20, and the tape handling device 30. The processor 90 contains a pre-stored calculation and analysis program. A preset height H is also pre-stored in the processor 90.

[0114] When the processor 90 determines that the height of the water hose stacking in the storage compartment 10 is not higher than the preset height H, when the second sensor 50 detects that the connector 110 is conveyed to the front top of the storage compartment 10 by the conveying device 20, the processor 90 determines that the cable management device 30 is performing a backward empty-walking action, and the processor 90 determines the front-back distance S determined by the front-back position of the connector 110 (located at the front top of the storage compartment 10, the position of which is known) and the front-back position of the cable management device 30 obtained from the second position sensor 70 satisfies S≤L0 / 2, the processor 90 controls the cable management device 30 to stop performing the current backward empty-walking action, or controls the cable management device 30 not to perform the clamping and pulling action after performing the current backward empty-walking action, so that the connector 110 can fall vertically from the drop port 101 to the rear bottom of the storage compartment 10.

[0115] When connector 110 passes through tape drop opening 101, first position sensor 60 can send a signal to processor 90, and processor 90 will then perform subsequent actions according to the actual situation.

[0116] In some embodiments, the fire hose recovery method further includes:

[0117] The water hose 100 is stacked in multiple storage spaces using the belt handling device 30, and the water hose 100 in each storage space is stacked to a preset height H. The multiple storage spaces are formed sequentially in the left and right directions within the storage compartment 10.

[0118] With the water hoses 100 in each storage space stacked to a preset height H, the hose handling device 30 moves back and forth synchronously while continuously and alternately performing the clamping and pulling action and the backward empty walking action.

[0119] It should be noted that the multiple tape storage spaces can be divided by the physical structure within the tape storage compartment 10. For example, multiple partition structures 103 can be arranged sequentially and at intervals along the left-right direction within the tape storage compartment 10, with each adjacent partition structure 103 forming a tape storage space. Alternatively, the multiple tape storage spaces can also be pre-divided within the program of the processor 90. When the processor 90 controls the tape organizing device 30 to organize the tape, the processor 90 can control the tape organizing device 30 to move left and right to different left and right positions, with each of these different left and right positions corresponding to a different tape storage space.

[0120] As can be seen from the steps of this embodiment, before the hose stacking height in each storage space reaches the preset height H, hoses are prioritized for stacking in the storage spaces where the hose stacking height has not yet reached the preset height H. When the hose stacking height in all storage spaces reaches the preset height H, the already stacked hoses can form a relatively flat support surface at the preset height H. Thus, the hose handling device 30 can repeatedly and alternately perform the clamping and pulling action and the backward empty walking action, and move back and forth synchronously from side to side, to achieve a "Z" shaped hose stacking method on this support surface.

[0121] When performing a "Z"-shaped hose stacking, the connector 110 does not necessarily have to be placed at the rear bottom of the hose storage compartment 10, for example, referring to... Figure 3 The two connectors 110 located at the front of the storage compartment 10 are both stacked in a "Z" shaped water hose stacking method.

[0122] The following examples illustrate alternative embodiments in which the steps in this embodiment can be performed:

[0123] In one alternative embodiment, the belt handling device 30 is movably disposed at the bottom of the conveyor 20. A left-right moving device (not marked in the figure, e.g., a left-right arranged screw and nut mechanism) drives the conveyor 20 and belt handling device 30 to move synchronously left and right. A third position sensor (not marked in the figure) detects the left-right position of the conveyor 20, and a height sensor 80 detects the stacking height of the water hose 100 in the storage compartment 10. A processor 90 communicates with the third position sensor, the height sensor 80, the conveyor 20, and the belt handling device 30. A preset height H is pre-stored in the processor 90.

[0124] Before the height sensor 80 detects that the water hose stacking height in all the storage space has reached the preset height H, the processor 90, based on the detection result of the height sensor 80, controls the left and right moving device (and based on the real-time feedback of the third position sensor) to drive the conveyor device 20 and the belt handling device 30 to move synchronously to directly above the storage space where the water hose stacking height has not reached the preset height H, and prioritizes stacking the water hose in the storage space.

[0125] When the height sensor 80 detects that the water hose stacking height in all the storage space has reached the preset height H, the processor 90, based on the detection result of the height sensor 80, controls the tape handling device 30 to continue to repeatedly and alternately perform the tape pulling action and the backward empty walking action, while simultaneously controlling the tape handling device 30 to move back and forth left and right, thereby realizing the "Z" shaped water hose stacking method.

[0126] In some embodiments, the fire hose recovery method further includes:

[0127] When the water hoses 100 in each storage space are stacked to a preset height H and the hose handling device 30 continues to perform a backward empty movement, when it is determined that the hose handling device 30 and the connector 110 can reach the drop port 101 at the same time, the hose handling device 30 will not perform a clamping and pulling action after completing the current backward empty movement.

[0128] Through the steps of this embodiment, interference between the tape feeding device 30 and the connector 110 can be avoided, thereby ensuring that the connector 110 can fall vertically from the tape drop outlet 101 to the rear bottom of the tape storage box 10.

[0129] For example, whether the connector 110 has reached the tape drop outlet 101 can be detected by the first position sensor 60, and the front and rear positions of the tape handling device 30 can be detected by the second position sensor 70. By setting the processor 90 to communicate with the first position sensor 60, the second position sensor 70, the conveyor 20 and the tape handling device 30, the processor can control the tape handling device 30 not to perform the tape clamping and pulling action after completing the current backward empty walking action when it is determined that the tape handling device 30 and the connector 110 can reach the tape drop outlet 101 at the same time.

[0130] A second exemplary embodiment of this application also provides a fire hose recovery system, which includes:

[0131] The tape storage compartment 10 has a tape drop outlet 101 at its rear top;

[0132] Conveying device 20 is used to convey water hose 100 from front to back to drop port 101;

[0133] The belt handling device 30 is movable back and forth at the bottom of the conveyor 20 and can clamp or release the water belt 100 inside the top of the belt storage box 10.

[0134] A left-right moving device is used to drive the conveyor device 20 to move left and right; and

[0135] The monitoring assembly can perform the above-mentioned fire hose retrieval method by monitoring the hose 100, the conveying device 20, the hose handling device 30, and the left and right moving device.

[0136] It should be noted that this application does not limit the specific composition of the monitoring assembly, as long as it can monitor the hose 100, the conveying device 20, the hose handling device 30 and the left and right moving device to perform the above-mentioned fire hose retrieval method.

[0137] In some embodiments, the monitoring assembly includes:

[0138] The first sensor 40 is used to detect whether the connector 110 enters the front end of the conveying device 20;

[0139] The second sensor 50 is used to detect whether the connector 110 is conveyed to the front top of the storage box 10 by the conveying device 20;

[0140] The first position sensor 60 is used to detect whether the connector 110 passes through the tape dropper 101;

[0141] The second position sensor 70 is used to detect the front and rear positions of the tape feeding device 30;

[0142] The third position sensor is used to detect the left and right positions of the conveyor 20;

[0143] Height sensor 80 is used to detect the stacking height of the water hose 100 in the storage compartment 10; and

[0144] The processor 90 communicates with the first sensor 40, the second sensor 50, the first position sensor 60, the second position sensor 70, the third position sensor, the height sensor 80, the conveyor 20, the belt feeding device 30, and the left and right moving device.

[0145] In some embodiments, the conveying device 20 includes a guide belt device 201 and a take-up belt device 202 connected front to back. The take-up belt device 202 extends from the front top of the storage box 10 to the drop-off port 101. The guide belt device 201 is telescopic. The monitoring assembly includes a length sensor for detecting the front and rear length of the guide belt device 201.

[0146] In some embodiments, the conveying device 20 includes a guide belt device 201 and a take-up belt device 202 connected front and rear. The take-up belt device 202 extends from the front top of the storage box 10 to the drop-off port 101. The front end of the take-up belt device 202 is provided with an openable front pressing mechanism 203, and the rear end of the take-up belt device 202 is provided with an openable rear pressing mechanism 204.

[0147] When the connector 110 enters the front end of the belt feeding device 201, the front pressing mechanism 203 opens to disengage from the water belt 100, and the rear pressing mechanism 204 remains closed to press the water belt 100. This ensures that the front pressing mechanism 203 avoids the connector 110 when it is transported to the front end of the belt taking device 202 (i.e., the front top of the belt storage box 10), and that the closed state of the rear pressing mechanism 204 ensures the stable transport of the water belt 100.

[0148] After the connector 110 passes the front end of the take-up device 202, the front pressing mechanism 203 immediately closes to press the water hose 100, and the rear pressing mechanism 204 opens to disengage from the water hose 100. This ensures that the rear pressing mechanism 204 avoids the connector 110 when it is transported to the rear end of the take-up device 202, thereby ensuring that the connector 110 can pass through the drop outlet 101. At the same time, the closed state of the front pressing mechanism 203 ensures the stable transport of the water hose 100.

[0149] Finally, it should be noted that the following steps are typically required during the preparation phase before recycling the water hose 100:

[0150] Extend the belt guide device 201 forward and open the top of the belt storage box 10;

[0151] The water hose 100 is placed on the guide belt device 201 and the take-up device 202 with manual assistance (at this time, the first joint is usually placed on the guide belt device 201 or the take-up device 202), and the rear end of the water hose 100 passes through the drop outlet 101, and the rear pressing mechanism 204 presses the water hose 100.

[0152] Move the belt feeding device 30 to the initial position in the front-back direction (usually the foremost end of the preset front-back travel L0) and put it in the open state. Whether the belt feeding device 30 is in the initial position in the front-back direction can be detected by the second position sensor 70.

[0153] The conveying device 20 (including the guide belt device 201 and the take-up belt device 202) is moved to an initial position in the left and right direction. Whether the conveying device 20 is in the initial position in the left and right direction can be detected by a third position sensor.

[0154] The third exemplary embodiment of this application also provides an emergency device, such as a hose-laying fire truck, which includes the aforementioned fire hose recovery system.
