Technical Field

[0001] The invention relates to the technical field of emergency rescue equipment, and in particular to a sandbag quick filling device used for flood control and emergency rescue. Background Art

[0002] In the context of frequent natural disasters, floods and waterlogging have brought huge losses and threats to human society. In the face of water floods and waterlogging disasters, it is particularly important to carry out rescue and disaster relief quickly and effectively. In the process of rescue and disaster relief, sandbags, as a simple and effective protective tool, are widely used in emergency measures such as embankment reinforcement and flood prevention. In actual operation, the filling efficiency of sandbags directly affects the speed and effect of rescue and disaster relief.

[0003] The traditional way of filling sandbags usually requires people to place sandbags one by one at the sand outlet under the sand bucket, and then use a shovel or other tools to fill the sand into the sand bucket and then into the sandbags. This process is not only time-consuming, labor-intensive, and inefficient. Especially when a large number of sandbags are needed for protection in a short period of time, the manual filling method seems to be inadequate, which seriously affects the efficiency of disaster relief.

DETAILED DESCRIPTION

[0029] like Figure 1 and Figure 2 As shown, the sandbag rapid filling device for flood control and rescue is mainly composed of a base 1, a sand bucket 3 and a filling unit 5.

[0030] like Figure 3 and Figure 4 As shown, the sand hopper 3 is fixedly arranged on the base 1, and its structural feature is a hopper body 3a with a large upper opening and a small lower opening. A sand outlet 3a1 is arranged at the bottom of the hopper body 3a, and an on-off device is installed at the sand outlet 3a1 for controlling the outflow of sand.

[0031] The filling unit 5 is slidably mounted on the base 1, and comprises a sandbag frame 5e and a pressing cover 5m, which are used to place and press the sandbags.

[0032] In order to realize the left and right sliding of the filling unit 5 , a guide rail 4 is arranged on the base 1 , and the filling unit 5 comprises a moving seat 5 a , a guide groove matching with the guide rail 4 is arranged at the bottom of the moving seat 5 a .

[0033] The sandbag rack 5e is installed on the moving seat 5a to ensure the stability of the sandbag during the filling process. This design solves the problem of position adjustment during the sandbag filling process and improves the filling efficiency.

[0034] When in use, the sand hopper 3 is filled with sand, the sandbag is placed in the sandbag rack 5e, the edge of the sandbag is pressed against the mouth of the sandbag rack 5e with the pressure cover 5m, the filling unit 5 is moved to the bottom of the water outlet 3a1, the on-off device is turned on, the sand in the sand hopper 3 is loaded into the sandbag, and when the sandbag is full, the on-off device is turned off, the filling unit 5 is moved out, the pressure cover 5m is opened, and the filled sandbag is taken out.

[0035] In order to further improve the filling efficiency, two sets of filling units 5 are arranged on the base 1. When one set of units is filling, the other set of units can prepare the next sandbag, realizing continuous operation and greatly shortening the filling time.

[0036] The bucket body 3a is fixedly connected to the support 2 through the legs 3a2 and stably mounted on the base 1. This design ensures the stability of the sand bucket 3 during the filling process and avoids shaking or tilting due to the weight of the sand.

[0037] The on-off device is electric, such as an electromagnetic on-off valve or a mechanical on-off device. The mechanical on-off device includes an on-off shaft 3b, a passive gear 3c, a driving gear 3d and an on-off motor 3e. The on-off shaft 3b is provided with a sand outlet hole 3b1, and the on-off motor 3e drives the driving gear 3d to mesh with the passive gear 3c to realize the rotation of the on-off shaft 3b, thereby controlling the outflow of sand. This design realizes the rapid opening and closing of the sand outlet of the sand hopper 3, and improves the filling efficiency.

[0038] like Figures 5 to 8 As shown, the loading unit 5 also includes a moving seat driving device, including a travel motor 5j, a driving gear 5k and a rack 5l. The rack 5l is fixed on the base 1, and the travel motor 5j is fixed on the moving seat 5a. The moving seat 5a can move left and right through the engagement of the driving gear 5k and the rack 5l. In addition, a moving seat limiting device is also provided, including a stopper 5g and a stopper 5h, which are respectively arranged at the left and right ends and the middle of the base 1 to ensure the accuracy and safety of the moving seat 5a during the movement.

[0039] The moving seat position detection device includes proximity switches 5b arranged at both ends of the base 1 and proximity switches 5i arranged in the middle, which are used to detect the position of the moving seat 5a.

[0040] The sandbag full detection device includes a fixing seat 5c, a spring 5d, a detection block 5e1 and a proximity switch 5f, and determines whether the sandbag is full by detecting the degree of descent of the sandbag rack 5e. These devices provide accurate signals for the control system and realize automatic control.

[0041] The gland 5m is hinged to the support 5o through the connecting rod 5n, and the support 5o is fixedly arranged on the connecting seat 5p. The connecting seat 5p is provided with a proximity switch 29 5q for detecting the pressing state of the gland 5m. When the gland 5m is closed, the connecting rod 5n changes from a vertical state to a horizontal state and enters the detection range of the proximity switch 29 5q, thereby triggering the control system to perform the next operation.

[0042] The sandbag rack 5e is composed of a bottom plate 5e2, a support rod 5e3 and a top plate 5e4. The top plate 5e4 and the gland 5m are in a circular ring structure. In order to facilitate the removal of the filled sandbag, a notch 5e4a is provided on the top plate 5e4. Accordingly, the support rod 5e3 is not provided at the corresponding position of the notch 5e4a. This design not only ensures the stability of the sandbag, but also facilitates the removal of the sandbag. If there is no notch design, the filled sandbag needs to be removed from the top of the sandbag rack 5e. If there is a notch design, the sandbag can be removed from the side.

[0043] In the initial state, the on-off device of the sand hopper 3 is in the off state, and the two sets of filling units 5 are respectively on the left and right sides of the base 1. The sandbag is placed in the sandbag rack 5e, the pressure cover 5m is closed, the pressure cover pressing detection device sends a signal, and the control system controls the movable seat driving device to drive the filling unit 5 to move to the bottom of the sand hopper 3. After moving to the right position, the movable seat position detection device sends a signal in place, the control system controls the on-off device of the sand hopper 3 to become connected, and sand begins to be loaded into the sandbag. When the sandbag is full, the sandbag full detection device sends a signal, the control system controls the on-off device to disconnect and drive the filling unit 5 to return to the initial position. Before the filling unit 5 at one end returns to the initial position, the filling unit 5 at the other end cannot move. When the filling unit 5 at one end returns to the initial position, the control system determines the pressure cover pressing state of the filling units 5 at both ends, and the filling unit 5 that first sends the pressing signal moves to the bottom of the sand hopper 3 to load sand. This cyclic operation greatly improves the filling efficiency and meets the needs of rapid filling in emergency situations such as flood control and rescue.
