Description

Technical Field

[0001] The invention relates to the technical field of automobile gas tank mounting racks, and in particular to a gas tank fixing rack for a CNG heavy truck. Background Art

[0002] The gas tank mounting bracket of CNG (compressed natural gas) heavy-duty trucks is an important component to ensure the safe driving of the vehicle. It is mainly used to fix and support the CNG gas tank to ensure that it will not be displaced or damaged during driving.

[0003] Currently, there is existing technology that can fix multiple gas cylinders in a frame-type manner and install them on the frame behind the cab. For example, the patent publication number is CN102381184A. Its main technical means is to connect the front, middle and rear rows of brackets through the upper, middle and lower three-layer gas cylinder brackets in the frame, and the front and rear rows of gas cylinders are divided into upper, middle and lower layers and fixed on the gas cylinder brackets with the help of fasteners. The brackets are all truss structures composed of steel pipes that are welded together. After analysis, the disadvantages of this technical solution are that: circular heat dissipation holes are mostly set on the side panels of the gas tank fixing frame. In order to ensure heat dissipation and ventilation, such circular heat dissipation holes are usually set with a larger diameter. Then, in rainy and snowy weather, rain and snow are very easy to drift into the heat dissipation holes. Long-term rain and snow erosion will cause corrosion of the gas tank mounting frame material, especially when the material of the mounting frame is not corrosion-resistant enough. Such corrosion will reduce the strength and durability of the mounting frame and increase the risk of accidents. In addition, rain and snow will cause condensed water to accumulate in the tank body or pipeline, which may not only block the voltage regulator or pipeline, but also accelerate corrosion. When the ambient temperature is low, rain and snow drifting into the heat dissipation holes are easy to freeze, and the change in temperature will directly affect the pressure of the gas in the gas tank. When the temperature drops, the gas pressure decreases, which may cause insufficient gas supply and thus affect the vehicle power. Based on this, the present invention provides a CNG heavy-duty truck gas tank fixing frame with a simple and ingenious structure, which can automatically adjust the shape of the heat dissipation holes in rainy and snowy weather with a low ambient temperature to prevent rain and snow from entering and accumulating in the fixing frame. Summary of the invention

[0004] The purpose of the present invention is to provide a CNG heavy truck gas tank fixing bracket to address the deficiencies in the prior art, so as to solve the technical problem that rain and snow easily enter the fixing bracket through the heat dissipation holes, accumulate on the gas tank and freeze.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A gas tank fixing rack for a CNG heavy truck, comprising: A vertical plate, wherein two vertical plates are connected by two side plates, and the two side plates are connected by two transverse plates, and the two transverse plates are connected to the two vertical plates, and the side plates are provided with a plurality of circular heat dissipation holes, and the side plates are provided with a plurality of ventilation holes, and the transverse plates are provided with a plurality of mounting frames for mounting gas tanks; An adjustment plate, wherein a plurality of adjustment plates arranged in a circumference are slidably mounted in each of the heat dissipation holes, and the adjustment plates are driven by a transmission assembly mounted on the side plate, and when the plurality of adjustment plates slide to be close to each other, a flow hole is formed in the heat dissipation hole, and the diameter of the flow hole is smaller than the diameter of the heat dissipation hole; and The humidity sensor is installed on the mounting frame and is used to monitor the ambient humidity at the installation location of the gas tank, and the humidity sensor is connected to the transmission component.

[0006] As a further solution of the present invention: a plurality of the transmission components correspond to a plurality of heat dissipation holes one by one, and the transmission components on the heat dissipation holes are connected to a plurality of adjustment plates arranged thereon.

[0007] As a further solution of the present invention: the transmission assembly comprises: A fixing ring fixed to the side plate, one end of each of the adjusting plates is rotatably mounted with a positioning shaft, and each of the positioning shafts is rotatably mounted on the fixing ring; and The rotating ring is coaxially connected to the fixed ring and driven to rotate by a driving source, the driving source is connected to the humidity sensor, and the ends of the plurality of adjustment plates away from the positioning shaft are rotatably mounted with connecting rods, and the plurality of connecting rods are rotatably mounted on the rotating ring.

[0008] As a further solution of the present invention: a temperature sensor is installed on the mounting frame, and the temperature sensor is connected to the driving source.

[0009] As a further solution of the present invention: a baffle is fixed on each of the adjustment plates, and when a plurality of adjustment plates slide to be close to each other, the baffles are located in the flow holes.

[0010] As a further solution of the present invention: a collecting box is installed on each of the adjusting plates, and the collecting box is engaged with the baffle, and a hollow portion is provided on the baffle.

[0011] As a further solution of the present invention: each of the collecting boxes is connected with a bellows, and several bellows are respectively connected with several guide pipes, the guide pipes are fixed on the side plates, the side plates are fixed with drainage pipes, and the guide pipes are connected with the drainage pipes.

[0012] As a further solution of the present invention: the drain pipe is connected to the flow pipe, and the flow pipe is connected to a water cooling pipeline fixed on the mounting frame.

[0013] Beneficial effects of the present invention: (1) In the present invention, the humidity of the environment at the gas tank installation location is monitored by a humidity sensor. When the humidity is lower than the threshold, the transmission assembly drives a plurality of adjustment plates on the same heat dissipation hole to rotate synchronously until two adjacent adjustment plates are in close contact with each other. At this time, the plurality of adjustment plates are in a closed state. At this time, the plurality of adjustment plate areas located at the axis of the heat dissipation hole are enclosed to form a flow hole, and the heat dissipation area is reduced. It can effectively intercept rain and snow in rainy and snowy weather, and prevent rain and snow from penetrating into the gas tank fixing frame and accumulating, causing the gas tank mounting frame material to be corroded. It also avoids the problem that rain and snow freeze on the surface of the gas tank at low temperature, affecting the gas pressure inside it and thus affecting the power of the CNG heavy truck; (2) In the present invention, when the humidity sensor detects that the ambient humidity at the gas tank installation location is lower than a threshold value, and the temperature sensor detects that the ambient temperature at the gas tank installation location is lower than a threshold value, the external controller receives signals from the two sensors and controls the drive source to start, thereby controlling the plurality of adjustment plates to gather to a closed state. In this way, the heat dissipation area can be controlled to decrease at low temperatures and low humidity, thereby blocking rain and snow and preventing the problem of rain and snow freezing inside the gas tank fixing frame in a low temperature environment. (3) In the present invention, rain and snow entering the flow hole will fall onto the baffle and be intercepted, and part of the rainwater and melted snow water will pass through the hollow part and enter the collection box to be collected, further avoiding the problem of condensed water flying in the gas tank fixing frame and contacting the surface of the gas tank and the surface of its installation material, reducing the possibility of material corrosion, and extending the service life of the gas tank fixing frame; (4) In the present invention, the condensed water in several collection boxes located on the same heat dissipation hole all flows in this way and finally converges into the drain pipe. The condensed water in the drain pipe flows into the water cooling pipeline through the circulation pipe, thereby realizing the reuse of the condensed water of rain and snow, thereby accelerating the heat dissipation of the gas tank and further reducing the impact of blocking rain and snow on the heat dissipation performance of the gas tank.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 6 As shown, the present invention is a gas tank fixing rack for a CNG heavy truck, comprising: A vertical plate 1, two vertical plates 1 are connected by two side plates 2, two side plates 2 are connected by two horizontal plates 3, and the two horizontal plates 3 are connected to the two vertical plates 1, a plurality of circular heat dissipation holes 6 are arranged on the side plates 2, and a plurality of ventilation holes 5 are arranged on the side plates 2, and a plurality of mounting frames 4 for mounting gas tanks are arranged on the horizontal plates 3; Adjustment plates 7, each of the heat dissipation holes 6 is slidably mounted with a plurality of adjustment plates 7 arranged in a circumference, and the adjustment plates 7 are driven by a transmission assembly 8 mounted on the side plate 2, and when the plurality of adjustment plates 7 slide to be close to each other, a flow hole 9 is formed in the heat dissipation hole 6, and the diameter of the flow hole 9 is smaller than the diameter of the heat dissipation hole 6; and The humidity sensor is installed on the mounting frame 4 and is used to monitor the ambient humidity at the location where the gas tank is installed. The humidity sensor is connected to the transmission assembly 8 .

[0019] In one case of this embodiment, the humidity sensor is a prior art, and this application does not improve it. Therefore, there is no need to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0020] When the present embodiment is actually applied, in the initial state, the plurality of adjustment plates 7 are in an open and closed state, and the distance between two adjacent adjustment plates 7 is the largest. At this time, the gas tank fixing frame relies on the heat dissipation holes 6 to dissipate heat, and the heat dissipation area is the largest; when the humidity sensor detects that the ambient humidity at the gas tank installation location is lower than the threshold value, the transmission assembly 8 starts and drives the plurality of adjustment plates 7 on the same heat dissipation hole 6 to rotate synchronously until two adjacent adjustment plates 7 are in close contact with each other. At this time, the plurality of adjustment plates 7 are in a closed state. At this time, the plurality of adjustment plates 7 located at the axis of the heat dissipation hole 6 enclose the flow hole 9, that is, the flow hole 9 is formed in the heat dissipation hole 6, and the diameter of the flow hole 9 is smaller than the diameter of the heat dissipation hole 6. At this time, the gas tank fixing frame relies on the flow hole 9 to dissipate heat, and can effectively intercept the rain and snow that is about to drift into the heat dissipation hole 6 in rainy and snowy weather, and prevent the rain and snow from penetrating into the gas tank fixing frame and accumulating inside, causing the material of the gas tank mounting frame 4 to be corroded. The problem of corrosion is avoided, and the problem of rain and snow freezing on the surface of the gas tank under low temperature affecting the gas pressure inside and then affecting the power of the CNG heavy truck is avoided; at the same time, the flow hole 9 is reserved for heat dissipation to ensure that the heat dissipation of the gas tank fixing frame will not be completely lost. Considering that the ambient temperature will drop in rainy and snowy weather, not to mention the low temperature weather that is prone to freezing, the heat load of the CNG heavy truck will be reduced at this time, so the heat dissipation workload of the gas tank fixing frame will also be reduced. Therefore, adaptively adjusting the heat dissipation area in rainy and snowy weather will not cause excessive heat load on the gas tank to affect the power of the CNG heavy truck. At the same time, this method can adaptively shield the gas tank, greatly reducing the rain and snow entering the heat dissipation hole 6; it should be noted that rain and snow can easily enter the heat dissipation hole 6 on the side during vehicle driving, while the ventilation hole 5 on the vertical plate 1 will not drift into rain and snow due to the obstruction of the cab and the influence of wind direction during driving.

[0021] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, the plurality of transmission components 8 correspond to the plurality of heat dissipation holes 6 one by one, and the transmission components 8 on the heat dissipation holes 6 are connected to the plurality of adjustment plates 7 arranged thereon.

[0022] like Figure 3-Figure 10 As shown, as a preferred embodiment of the present invention, the transmission assembly 8 includes: A fixing ring 801 fixed on the side plate 2, a positioning shaft 802 is rotatably mounted on one end of the plurality of adjustment plates 7, and a plurality of positioning shafts 802 are rotatably mounted on the fixing ring 801; and The rotating ring 803 is coaxially rotatably connected to the fixed ring 801 and is driven to rotate by a driving source, and the driving source is connected to the humidity sensor. The ends of several adjustment plates 7 away from the positioning shaft 802 are rotatably installed with connecting rods 804, and several connecting rods 804 are rotatably installed on the rotating ring 803.

[0023] A limiting rod 805 is fixed on the rotating ring 803 , and the limiting rod 805 is slidably installed on the fixing ring 801 .

[0024] It should be noted that each of the transmission components 8 includes a driving source, and each heat dissipation hole 6 initially has a driving source; of course, a linkage component such as a belt can also be used to connect the rotating rings 803 on several heat dissipation holes 6, where one rotating ring 803 is connected to a driving source, and several rotating rings 803 can be controlled to rotate synchronously by one driving source, and no specific limitation is made here.

[0025] In one case of this embodiment, the driving source may be a motor assembly, or a gear assembly or a pulley assembly driven by a motor, as long as it can cause the rotating ring 803 to rotate. This embodiment does not make any specific limitations here.

[0026] In actual application of this embodiment, when the humidity sensor detects that the ambient humidity at the installation location of the gas tank is lower than the threshold value, the driving source controls the rotating ring 803 to rotate a certain angle, and the rotating ring 803 drives the adjustment plate 7 to rotate through the connecting rod 804. Since one end of the adjustment plate 7 is limited by the positioning shaft 802, the adjustment plate 7 is driven to rotate with the central axis of the positioning shaft 802 as the axis until two adjacent adjustment plates 7 are tightly attached to each other and in a closed state, which can reduce the possibility of rain and snow entering the gas tank fixing frame.

[0027] like Figure 1-Figure 2 As shown, as a preferred embodiment of the present invention, a temperature sensor is installed on the mounting bracket 4, and the temperature sensor is connected to the driving source.

[0028] In one case of this embodiment, the temperature sensor, humidity sensor and driving source are all connected to an external controller. The above components are all prior art and this application does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of this application.

[0029] In actual application of this embodiment, when the humidity sensor detects that the ambient humidity at the installation location of the gas tank is lower than the threshold, and at the same time the temperature sensor detects that the ambient temperature at the installation location of the gas tank is lower than the threshold, the external controller receives the signals sent by the two, and controls the drive source to start, and then controls the plurality of adjustment plates 7 to gather to a closed state. In this way, the heat dissipation area can be controlled to be reduced at low temperatures and low humidity, thereby blocking rain and snow and avoiding the problem of insufficient heat dissipation performance of the gas tank.

[0030] like Figure 4-Figure 10 As shown, as a preferred embodiment of the present invention, a baffle 10 is fixed on each of the adjustment plates 7 , and when a plurality of adjustment plates 7 slide to be close to each other, a plurality of baffles 10 are located in the flow hole 9 .

[0031] Among them, the baffle 10 is located in the central extension direction of the circulation hole 9, which is equivalent to increasing the thickness of the circulation hole 9. When rain and snow drift into the circulation hole 9, they will fall on the baffle 10, thereby preventing rain and snow from further penetrating into the gas tank fixing frame, thereby preventing rain and snow from corroding the gas tank mounting frame 4 material, and can also prevent the problem of rain and snow freezing on the surface of the gas tank or its mounting frame 4 material in a low temperature environment.

[0032] In one case of this embodiment, a collecting box 11 is installed on each of the adjusting plates 7 , and the collecting box 11 is engaged with the baffle 10 , and a hollow portion is provided on the baffle 10 .

[0033] In actual application of this embodiment, during the driving of the vehicle, rain and snow entering the circulation hole 9 will fall onto the baffle 10 and be intercepted, and part of the rainwater and melted snow water will pass through the hollow part into the collection box 11 and be collected, thereby further avoiding the problem of condensed water flying in the gas tank fixing frame and contacting the surface of the gas tank and the surface of its installation material, reducing the possibility of material corrosion, and extending the service life of the gas tank fixing frame.

[0034] like Figure 8-Figure 10 As shown, as a preferred embodiment of the present invention, each of the collecting boxes 11 is connected to a bellows 13, and several bellows 13 are respectively connected to several guide pipes 12, the guide pipes 12 are fixed on the side plate 2, the side plate 2 is fixed with a drain pipe 14, and the guide pipe 12 is connected to the drain pipe 14.

[0035] In one case of this embodiment, the drain pipe 14 is connected to the flow pipe 15 , and the flow pipe 15 is connected to a water cooling pipeline fixed on the mounting frame 4 .

[0036] Among them, a drainage pump is provided on the drainage pipe 14, and the drainage pump and the water cooling pipeline are connected to an external controller. Cooling water flows in the water cooling pipeline, and its surface is in contact with the surface of the gas tank. The drainage pump and the water cooling pipeline are both existing technologies, and this application does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0037] In actual application of this embodiment, the condensed water in the collecting box 11 flows into the guide pipe 12 through the bellows 13. The condensed water in several collecting boxes 11 located on the same heat dissipation hole 6 all flows in this way and finally merges into the drain pipe 14. The condensed water in the drain pipe 14 flows into the water cooling pipeline through the circulation pipe 15, thereby realizing the reuse of condensed water from rain and snow, thereby accelerating the heat dissipation of the gas tank and further reducing the impact of blocking rain and snow on the heat dissipation performance of the gas tank. It should be noted that when several adjustment plates 7 are in an open and closed state, the corresponding several bellows 13 are in a folded state, and when several adjustment plates 7 are in a closed state, the corresponding several bellows 13 are in a stretched state.

[0038] Working principle of the present invention: The above embodiment of the present invention provides a gas tank fixing bracket for CNG heavy-duty trucks. When the humidity sensor detects that the ambient humidity at the gas tank installation location is lower than the threshold value, the transmission assembly 8 starts and drives several adjustment plates 7 on the same heat dissipation hole 6 to rotate synchronously until two adjacent adjustment plates 7 are tightly attached to each other. At this time, several adjustment plates 7 are in a closed state. At this time, several adjustment plates 7 located at the axis of the heat dissipation hole 6 are surrounded to form a flow hole 9, that is, a flow hole 9 is formed in the heat dissipation hole 6, and the diameter of the flow hole 9 is smaller than the diameter of the heat dissipation hole 6. At this time, the gas tank fixing bracket relies on the flow hole 9 for heat dissipation, and can effectively intercept rain and snow that are about to drift into the heat dissipation hole 6 in rainy and snowy weather, avoiding rain and snow from accumulating deep into the gas tank fixing bracket, causing the gas tank mounting bracket 4 material to be corroded, and also avoiding the problem of rain and snow freezing on the surface of the gas tank at low temperature, affecting the gas pressure inside it and thus affecting the power of the CNG heavy-duty truck.

[0039] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
