Description

[0002] Oil tank is usually used for storing a large amount of oil, and the bottom plate is the basic part of the oil tank. If the bottom plate leaks, oil will flow out from the damaged part. At this time, if it is not handled in time, it will cause oil spill, which may cause environmental pollution, fire and explosion risks.

[0003] When the oil tank bottom plate is damaged and oil spills from the damaged part, and the oil in the tank cannot be emptied immediately, the only way to stop oil spill in an emergency situation is to quickly supplement the water in the oil tank. Water is injected into the bottom of the oil tank to raise the water level, and the water cushion is formed by using the characteristics that the density of water is greater than that of oil. The density of water is about 1g / cm 3 , and the density of oil such as crude oil and diesel is usually less than that of water (about 0.8-0.9g / cm 3 ). By injecting fire water into the bottom of the tank, the water will sink to the bottom, lifting the oil upwards and preventing the oil from continuing to spill. Therefore, the main purpose of water supply is to balance the pressure difference between the inside and outside by increasing the pressure of the water at the bottom, and to reduce or stop the leakage of oil. How to quickly supplement the water in the oil tank in an emergency situation becomes the key to the emergency disposal of oil spill caused by the damage of the oil tank bottom plate.

[0044] In the present example, the specific working principle of the oil tank emergency water replenishing device is as follows: in use, the water inlet pipe joint 6 is first connected to the flange connecting disc 4, then the first connecting arc plate 7 and the second connecting arc plate 8 are opened and sleeved outside the water inlet pipe joint 6, and then the first connecting arc plate 7 and the second connecting arc plate 8 are closed, then a plurality of connecting bolt columns 12 are aligned with the connecting holes and inserted into the connecting holes of the flange connecting disc 4, then the workers rotate the connecting sleeve 15 through the first handle 16 to drive the driving gear 13 to rotate, the driving gear 13 drives a plurality of gear nuts 14 to rotate, and then the plurality of gear nuts 14 are threadedly connected outside the plurality of connecting bolt columns 12 to complete the connection of the water inlet pipe joint 6 and the flange connecting disc 4.

[0045] Example Two

[0046] Please refer to Figures 5-8, the quick connecting mechanism further comprises a third connecting arc plate 17 and a fourth connecting arc plate 18 which are rotationally connected with each other, the connecting plates 11 on both sides are respectively slidably connected to the inner sides of the third connecting arc plate 17 and the fourth connecting arc plate 18, and the gear nuts 14 are respectively rotationally connected to one end of the third connecting arc plate 17 and the fourth connecting arc plate 18 close to the driving gear 13. In this embodiment, the quick connecting mechanism is designed in an integrated manner, the connecting plates 11 slide on the inner sides of the third connecting arc plate 17 and the fourth connecting arc plate 18, and when in use, the third connecting arc plate 17 and the fourth connecting arc plate 18 can be first opened, and the connecting plates 11 can be moved to the side of the third connecting arc plate 17 and the fourth connecting arc plate 18 away from the gear nuts 14. After the water inlet pipe joint 6 is butted with the flange connecting disc 4, the third connecting arc plate 17 and the fourth connecting arc plate 18 are wrapped outside the water inlet pipe joint 6 and the flange connecting disc 4, and the third connecting arc plate 17 and the fourth connecting arc plate 18 are closed, so that the inner end faces of the third connecting arc plate 17 and the fourth connecting arc plate 18 abut on the side end face and the outer end face of the gear nut 14. At this time, the connecting bolt columns 12 do not affect the closing of the third connecting arc plate 17 and the fourth connecting arc plate 18, that is, the connecting bolt columns 12 do not interfere with the water inlet pipe joint 6 when the third connecting arc plate 17 and the fourth connecting arc plate 18 are closed. When the third connecting arc plate 17 and the fourth connecting arc plate 18 are wrapped outside the flange connecting disc 4 and are in a closed state, the gear nuts 14 are just meshed and connected on the outer periphery of the driving gear 13, and the corresponding gear nuts 14, connecting holes and connecting bolt columns 12 have the same central axis.

[0047] It should be noted that the third connecting arc plate 17 or the fourth connecting arc plate 18 has the same central axis as the connecting plate 11, and the connecting bolt columns 12 and the connecting plate 11 have the same central axis in space. Through the sliding connection of the connecting plate 11 and the third connecting arc plate 17 or the fourth connecting arc plate 18, the connecting plate 11 can move along the axis direction of the connecting bolt column 12, thereby improving the accuracy of the connection between the connecting bolt column 12, the connecting hole and the gear nut 14, and improving the efficiency of the butt joint.

When the third connecting arc plate 17 and the fourth connecting arc plate 18 are sleeved outside the flange connecting disc 4 and the water inlet pipe joint 6 and are in the closed state, the first connecting rod 9 is rotated to move into the accommodating groove of the fourth connecting arc plate 18, and the lock sleeve 10 is rotated to abut against the end face of the fourth connecting arc plate 18, so that the third connecting arc plate 17 and the fourth connecting arc plate 18 are locked, the central axes of the connecting bolt column 12 and the corresponding gear nut 14 are more aligned, the misalignment degree of the central axes between the two is smaller, and the probability of the jamming between the inner thread of the gear nut 14 and the outer thread of the connecting bolt column 12 due to the slight misalignment of the central axes of the connecting bolt column 12 and the gear nut 14 is reduced.

[0049] Please refer to Figures 5-8 The outer walls of the third connecting arc plate 17 and the fourth connecting arc plate 18 are provided with a plurality of guide grooves 21, and the outer wall of the connecting plate 11 is fixed with a plurality of second connecting rods 19 matched with the guide grooves 21. The connecting plate 11 is slidingly connected with the corresponding third connecting arc plate 17 or fourth connecting arc plate 18 through the cooperation of the second connecting rod 19 and the guide groove 21. When the third connecting arc plate 17 and the fourth connecting arc plate 18 are in the closed state, the plurality of second connecting rods 19 intersect with the central axes of the third connecting arc plate 17 and the fourth connecting arc plate 18. The outer side of the second connecting rod 19 is threadedly connected with a positioning ring 22, and the positioning ring 22 is slidingly connected inside the corresponding guide groove 21.
