[0052] As can be seen from the above, by setting up a fire sand truck to meet the fire sand preparation needs of the gas well station, by setting up a box 10 with multiple rollers 20 to store the fire sand, the integrated function of fire sand storage and transportation is realized, which is convenient for moving and pushing, reduces the labor intensity of fire sand transportation, and improves the timeliness of emergency rescue. By setting a drive component 40 to drive the movement of the valve core 30 to control the opening and closing of the sand outlet 120, and using a limiter 50 to fix the drive component 40, the sand outlet 120 can be kept in an open state, and continuous sand spreading is achieved, which further reduces the labor intensity of rescue personnel, improves the efficiency of fire sand laying, and provides protection for the safe production of the gas well station.
[0053] It should be noted that the box 10 is in a cubic shape and includes four side surfaces. The limiter 50 is disposed on one of the side surfaces. The size of the box 10 is set according to actual needs. The larger the size of the box 10, the more firefighting sand it can accommodate. For example, the size of the box 10 is designed to accommodate 1.2 tons of firefighting sand when fully loaded.
[0054] It should also be noted that if Figure 1 , Figure 2 As shown, there are four rollers 20, which are respectively arranged at the four corners of the bottom of the box body 10, wherein the two rollers 20 on the side away from the push handle 90 are directional wheels, and the two rollers 20 on the side close to the push handle 90 are universal wheels, thereby realizing the movement and steering of the fire sand truck.
[0055] It should also be noted that if Figure 1 , Figure 2 As shown, the height direction is parallel to the Z direction, the length direction is parallel to the X direction, and the width direction is parallel to the Y direction.
[0056] It should also be noted that a valve seat 310 is provided in the sand outlet hole 120. The valve seat 310 is used to support the fully closed position of the valve core 30 and constitute a sealing pair. When the sand outlet hole 120 is closed, the valve core 30 abuts against the valve seat 310. In addition, the specific structure of the valve seat 310 and the specific principle of cooperation between the valve seat 310 and the valve core 30 are both existing technologies and will not be repeated in this application.
[0057] like Figure 1 , Figure 3 As shown, in some embodiments, the fire sand truck includes a guide frame 60 and a guide rod 70; the guide frame 60 is arranged at the bottom of the box body 10 and is located inside the box body 10; the guide rod 70 is arranged on the guide frame 60 and is coaxially arranged with the sand outlet hole 120; wherein, the guide rod 70 is penetrated through the valve core 30.
[0058] The guide frame 60 and the guide rod 70 are provided to provide a structural basis for the movement of the valve core 30 , and the guide rod 70 is used to play a guiding role, so that the valve core 30 can move stably in the height direction.
[0059] It should be noted that the guide frame 60 is arranged around the sand outlet hole 120 ; and the valve core 30 is provided with a guide hole for the guide rod 70 to pass through.
[0060] like Figure 1 As shown, in some embodiments, the valve core 30 is truncated cone-shaped, the diameter of the upper end surface of the valve core 30 is D1, the diameter of the lower end surface of the valve core 30 is D2, and the inner diameter of the sand outlet hole 120 is D3, wherein D3<D2<D1.
[0061] By setting the diameter of the valve core 30 and the inner diameter of the sand outlet hole 120 , it is ensured that the valve core 30 can block the sand outlet hole 120 , so that the box body 10 has the function of storing fire-fighting sand.
[0062] like Figure 1 As shown, in some embodiments, the drive assembly 40 includes a first rod 410, a second rod 420 and a third rod 430; one end of the first rod 410 is connected to the bottom of the box body 10, and the first rod 410 extends in the height direction; one end of the second rod 420 extends into the sand outlet hole 120 and abuts against the bottom of the valve core 30; the third rod 430 has a bending angle, one end of the third rod 430 is connected to an end of the second rod 420 away from the valve core 30, and the bending angle of the third rod 430 is hinged to the first rod 410; wherein, in the sand spreading state, the third rod 430 abuts against the limit member 50; in the sand storing state, the third rod 430 abuts against the bottom of the box body 10.
[0063] The lever structure is formed by setting the first rod 410 and the third rod 430, and the first rod 410 is used as the fulcrum of the lever structure to play a supporting role; by pressing the third rod 430 downward, the third rod 430 rotates clockwise, the second rod 420 moves with the third rod 430, the second rod 420 pushes up the valve core 30, and the valve core 30 moves upward along the guide rod 70, so that the sand outlet hole 120 is opened, providing a structural basis for sand spreading. In addition, the limiting member 50 is abutted against the third rod 430 to prevent the third rod 430 from rebounding under the gravity of the valve core 30, and the third rod 430 is fixed, so that the sand outlet hole 120 remains open, and continuous sand spreading is achieved; when the limiting member 50 is rotated so that the limiting member 50 does not abut against the third rod 430, the valve core 30 falls under the action of gravity, driving the third rod 430 to rotate counterclockwise, and the valve core 30 blocks the sand outlet hole 120.
[0064] like Figure 1As shown, in some embodiments, the third rod member 430 includes an upper rod segment 4301 and a lower rod segment 4302 connected to one end of the upper rod segment 4301, and the end of the lower rod segment 4302 away from the upper rod segment 4301 is connected to the second rod member 420; wherein the bending angle is located between the upper rod segment 4301 and the lower rod segment 4302, and the bending angle is greater than 90° and less than 180°.

By setting the length of the first limiting section 510 to be greater than the second limiting section 520, the weight of the first limiting section 510 is greater than that of the second limiting section 520, thereby ensuring that when the limiting member 50 abuts against the third rod 430, the third rod 430 can be effectively fixed to prevent the third rod 430 from rebounding under the gravity of the valve core 30.
[0069] It should also be noted that if Figure 2 As shown, the notch 530 is an arc notch 530 , and the arc notch 530 is provided to match the shape of the upper rod section 4301 .

[0072] It should be noted that the cross section is a cross section perpendicular to the width direction, that is, a cross section perpendicular to the Y direction.
[0073] like Figure 1 , Figure 2 As shown, in some embodiments, the opening of the sand storage chamber 110 is located at the top of the box body 10; wherein the fire sand truck further includes a cover 80 disposed on the top of the box body 10, and the cover 80 is used to cover the opening.
[0074] The cover 80 is provided to prevent rainwater from dripping in and causing the fire fighting sand to become compacted.
[0075] It should be noted that the cover 80 is directly covered on the top of the box body 10 for easy removal.
[0076] like Figure 1 , Figure 3 As shown, in some embodiments, the fire fighting sand truck further includes a push handle 90 disposed on a side of the box body 10 .
[0077] The push handle 90 is provided to facilitate the rescue personnel to push the fire fighting sand truck to move.
