Description
Technical Field
[0001] The utility model relates to the technical field of fuel tanks, and particularly relates to a spare semi-trailer fuel tank. Background Technique
[0002] A semi-trailer is towed forward by a tractor and does not have its own power system, so generally there is no need to set up a fuel tank. However, in the face of Africa or underdeveloped regions, the number of gas stations is small and the distance between them is far. Relying only on the fuel tank of the tractor, it is very easy to run out of fuel midway. To solve this problem, it is necessary to suspend a spare fuel tank at the bottom of the semi-trailer.
[0003] The existing spare fuel tank is relatively long. When the fuel tank follows the semi-trailer running, when turning or the vehicle jolts, the oil in the spare fuel tank will shake under the action of inertia. The shaking oil impacts the side wall of the fuel tank, which will not only generate noise, but also the oil will instantly concentrate at one end of the fuel tank, which is extremely easy to cause the vehicle to lose balance and pose a danger of vehicle rollover. Content of the Utility Model
[0004] The purpose of the utility model is to provide a spare semi-trailer fuel tank, which reduces the power of the oil impacting the side wall of the fuel tank by increasing the resistance of the oil flow, thereby reducing noise and avoiding the situation that the oil instantly concentrates at one end of the fuel tank and causes the vehicle to lose balance.
[0005] To achieve the above purpose, the utility model provides a spare semi-trailer fuel tank, which includes a sealed box body. An oil inlet is arranged at the top of the box body, and an oil outlet is arranged at the bottom. An oil cap is installed on the oil inlet, and a valve is arranged on the oil outlet; a plurality of anti-surge plates are evenly arranged in the inner cavity of the box body along its length direction, and the anti-surge plates divide the inner cavity of the box body into several small chambers; a bottom arc-shaped groove is arranged at the bottom of the anti-surge plate, and a bottom liquid passing channel is formed between the bottom arc-shaped groove and the bottom of the box body, and the bottom liquid passing channel communicates with adjacent small chambers.
[0006] After adopting the above structure, oil is injected into the box body through the oil inlet; when it is necessary to drain the oil, the valve at the oil outlet is opened, and the oil is discharged from the oil outlet; the length direction inside the fuel tank is divided into several small chambers by the anti-surge plates, and adjacent small chambers are communicated through the bottom liquid passing channel; when turning or the vehicle jolts, causing the oil to shake, the anti-surge plates play a certain blocking effect on the oil, buffer the impact of the oil, and consume the kinetic energy of the oil, thereby reducing the noise generated by the oil colliding with the box body, and at the same time avoiding the situation that the oil quickly gathers at one end of the fuel tank and causes the vehicle to lose balance.
[0007] When the spare fuel tank is full of oil, in order to avoid the excessive impact of the shaking oil on the top of the anti-surge plate, a top arc-shaped groove is arranged at the top of the anti-surge plate, and a top liquid passing channel is formed between the top arc-shaped groove and the top of the box body, and the top liquid passing channel communicates with adjacent small chambers.
[0008] In order to increase the contact area between the wave baffle and the side wall of the box body, facilitate the fixation of the two, and at the same time enable the wave baffle to play a certain supporting role for the box body, flanges that are in contact with the side wall of the box body are provided around the wave baffle, and the flanges are perpendicular to the wave baffle.
[0009] In order to disperse the liquid passage as much as possible on the premise of ensuring a certain liquid flow rate and enable the wave baffle to play the maximum wave prevention role, two bottom arc grooves are provided at the bottom of the wave baffle, and the two bottom arc grooves are respectively located on both sides of the bottom of the wave baffle; two top arc grooves are also provided at the top of the wave baffle, and the two top arc grooves are respectively located on both sides of the top of the wave baffle.
[0010] In order to prevent the corner positions of the box body from being collided and deformed, chamfers are provided at the four corners of the box body.
[0011] In order to increase the support of the wave baffle for the chamfer position of the box body and further improve the strength of the box body, avoiding angles that cooperate with the chamfers are provided at the four corners of the wave baffle; the flanges do not cover the avoiding angle positions.
[0012] In order to prevent oil theft, a fuel tank lock box is provided outside the oil inlet and the oil outlet, and the fuel tank lock box is locked with the box body through a fuel tank lock.
[0013] In order to reduce the number of side walls of the box body and thus reduce the welding workload, the box body includes an L-shaped upper box body and an L-shaped lower box body. The upper box body and the lower box body are relatively buckled into a square cylinder, and the overlapping sides are overlapped with each other and are welded together completely.
[0014] In order to achieve the rapid splicing of the side plate and the box body, and at the same time reduce the gap and facilitate the welding operation, the box body also includes side plates located on both sides of the upper box body and the lower box body. The periphery of the side plate is provided with bending edges that are inserted into the square cylinder and are welded together completely with the square cylinder. Open slots for avoiding the overlapping edges of the box body and the lower box body are provided on the bending edges.
[0015] In order to ensure the impact resistance of the side plate, a transition inclined surface is provided between the bending edge and the side plate.
[0016] After adopting the above technical solution, the beneficial effects of the present utility model are as follows:
[0017] A spare semi-trailer fuel tank of the present utility model solves the technical problem that in the prior art, the oil in the spare fuel tank of the trailer sways with the vehicle, and the oil impacts the side wall of the fuel tank, which will not only generate noise, but even cause the vehicle to lose balance and cause danger.

Specific embodiments
[0025] The present utility model will be further described below with reference to the accompanying drawings.
[0026] The orientations referred to in this specification are based on the orientation of a spare semi-trailer fuel tank of the present utility model during normal operation, without limiting its orientation during storage and transportation, only representing the relative positional relationship and not the absolute positional relationship.
[0027] As Figure 1 and Figure 2 jointly show, a spare semi-trailer fuel tank includes a sealed box body 1. The sealed box body 1 is a rectangular structure in this embodiment, and a square or other structures can be adopted in practical applications; an oil inlet 11 is provided at the top of the box body 1, and an oil cap is installed on the oil inlet 11; an oil outlet 12 is provided on one side of the bottom of the box body 1, an oil outlet pipe is connected to the oil outlet 12, and a valve is provided on the oil outlet pipe.
[0028] A plurality of anti-wave plates 2 are uniformly arranged in the inner cavity of the box body 1 along its length direction, and the anti-wave plates 2 divide the inner cavity of the box body 1 into several small chambers; in this embodiment, two anti-wave plates 2 are provided, and the two anti-wave plates 2 divide the inner cavity of the box body 1 into three small chambers. In practical applications, three or four anti-wave plates 2 can also be provided, and this embodiment does not limit this.
[0029] The bottom of the wave baffle 2 is provided with a bottom arc groove 211. A bottom liquid passing channel is formed between the bottom arc groove 211 and the bottom of the box body 1, and the bottom liquid passing channel communicates with adjacent small chambers.
[0030] The top of the wave baffle 2 is provided with a top arc groove 212. A top liquid passing channel is formed between the top arc groove 212 and the top of the box body 1, and the top liquid passing channel communicates with adjacent small chambers.
[0031] In this embodiment, two bottom arc grooves 211 are provided at the bottom of the wave baffle 2, and the two bottom arc grooves 211 are respectively located on both sides of the bottom of the wave baffle 2; two top arc grooves 212 are also provided at the top of the wave baffle 2, and the two top arc grooves 212 are respectively located on both sides of the top of the wave baffle 2. By providing two bottom arc grooves 211 at the bottom and two top arc grooves 212 at the top, it can ensure sufficient liquid passing flow rate while not affecting the wave prevention effect of the wave baffle 2.
[0032] The fuel tank is fixed to the bottom of the semi-trailer by steel bar suspension rods; oil is injected into the interior of the box body 1 through the oil inlet 11; when oil needs to be discharged, the valve of the oil outlet pipe is opened, and the oil liquid is discharged from the oil outlet 12. Because the bottom and the top are communicated between each small chamber, the liquid level height of the oil liquid in each small chamber is the same. When the vehicle jolts and causes the oil liquid to shake, the oil liquid can interact between adjacent small chambers through the arc grooves 21 at the bottom and the top, ensuring that the oil liquid in the box body 1 maintains the same horizontal height. The wave baffle 2 has a certain blocking effect on the oil liquid, plays a buffering role on the impact of the oil liquid, reduces the noise generated by the oil liquid colliding with the box body 1, and at the same time avoids the oil liquid quickly gathering at one end of the fuel tank, causing the vehicle to lose balance.
[0033] As Figure 1 、 Figure 2 and Figure 3 Collectively shown, chamfers 10 are provided at the four corners of the box body 1. The chamfers 10 avoid the problem that the corner positions are prone to deformation when the box body 1 collides. Chamfer-avoiding corners 23 that cooperate with the chamfers 10 are provided at the four corners of the wave baffle 2, and the chamfer-avoiding corners 23 support the positions of the chamfers 10, thereby further improving the strength of the box body 1.
[0034] As Figure 1 、 Figure 2 and Figure 3As shown together, flanging 22 that adheres to the side wall of the box body 1 is provided around the wave baffle 2, and the flanging 22 is perpendicular to the wave baffle 2. By setting the flanging 22, the welding area with the side wall of the box body 1 is increased, thereby improving the fixing strength between the wave baffle 2 and the box body 1 and preventing the wave baffle 2 from detaching from the box body 1; in addition, the flanging 22 is perpendicular to the wave baffle 2, which plays a certain supporting role for the inner cavity of the box body 1 and improves the overall strength of the box body 1. For the convenience of installation, the flanging 22 does not cover the position of the wave baffle 2.
[0035] The box body 1 includes an L-shaped upper box body 13 and an L-shaped lower box body 14. The upper box body 13 and the lower box body 14 are buckled opposite to each other to form a square cylinder, and the overlapping edges between them overlap with each other and are fully welded. The L-shaped upper box body 13 and the L-shaped lower box body 14 are formed by bending, thereby reducing the number of overlapping edges, reducing the welding workload, and avoiding the damage to the box body caused by welding.
[0036] Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown together, since the square cylinder is formed by buckling the L-shaped upper box body 13 and the L-shaped lower box body 14, there is a height difference in the wall thickness at the overlapping edge. To make up for this height difference, as Figure 3 、 Figure 4 and Figure 5 As shown together, the box body 1 further includes side plates 15 located on both sides of the upper box body 13 and the lower box body 14. Bending edges 151 that are inserted into the square cylinder and are fully welded to the square cylinder are provided around the side plates 15. Open slots 152 for avoiding the overlapping edges of the upper box body 13 and the lower box body 14 are provided on the bending edges 151. Since there are two overlapping edges between the upper box body 13 and the lower box body 14, two open slots 152 are also provided, which are respectively located at the diagonal positions of the side plates 15. Due to the setting of the chamfer 10 position, avoiding slots 153 are also provided on the bending edges 151, and transition plates 154 are filled in the avoiding slots 153. The peripheries of the transition plates 154 are welded in the avoiding slots 153, so that the bending edges 151 can be smoothly inserted into the square cylinder. A transition inclined surface 155 is provided between the bending edges 151 and the side plates 15.
[0037] To prevent thieves from stealing oil, a fuel tank lock box 3 is provided outside the oil inlet 11 and the oil outlet 12, and the fuel tank lock box 3 is locked with the box body 1 through a fuel tank lock.
[0038] Of course, the above description is not a limitation to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also belong to the protection scope of the present invention.
