Description

Technical Field

[0001] The utility model relates to the field of pump vehicles, in particular to a mobile liquid injection vehicle. Background Art

[0002] The mobile liquid injection vehicle is a small mobile pump vehicle that can be used for pressurized injection of liquid media and pressurized injection of gel media. According to the relevant technology, in order to make the pump machine more flexible, the pump machine is usually installed on a movable trolley, on which a liquid storage tank for the medium to be pumped out and a pipe connecting the liquid storage pipe and the pump machine are installed. In order to make the liquid storage tank have a larger capacity, a rectangular tank body is usually used to be installed on the trolley. It has the advantages of large capacity and easy installation.

[0003] A Chinese patent with patent number CN212536043U discloses a mobile liquid injection vehicle, which relates to the technical field of pump vehicles. It includes a mobile vehicle, a pumping device installed on the mobile vehicle, a liquid storage tank installed on the mobile vehicle, and pipes installed at the input and output ends of the pumping device. The bottom of the liquid storage tank is recessed toward the mobile vehicle to form a concave bottom, and the lowest point of the concave bottom is connected to the pipe connected to the input end of the pumping device.

[0004] Although the mobile liquid injection vehicle described in the above patent can be designed into a spherical structure at the bottom of the liquid storage tank when in use, and electromagnetic heating is used to achieve sufficient discharge of liquid material from the liquid storage tank, on the one hand, the electromagnetic heating method is used to heat the entire liquid storage tank as a whole, which consumes a lot of energy. On the other hand, after heating, the liquid material itself still has a certain viscosity. When the liquid material in the liquid storage tank is close to being emptied, some liquid material in the liquid storage tank will still adhere to the inner wall of the liquid storage tank and cannot be discharged, thereby causing waste of liquid material.

[0015] By adopting the above technical solution, the lifting mechanism is mainly used to realize the lifting and lowering of the cover plate, so as to add materials into the storage tank and facilitate the cleaning of the storage tank.

[0016] Furthermore, the boss is welded to the cover plate, and the boss is an arc-shaped block structure.

[0017] By adopting the above technical solution, it can be ensured that the boss rises and falls synchronously with the cover plate.

[0018] Furthermore, a push handle is welded to the upper end of the mobile base located on one side of the storage tank, and the mobile base is composed of a base plate and self-locking universal wheels installed at the four corners of the bottom end of the base plate.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] The utility model installs a blowing and scraping mechanism on the cover plate of the storage tank, so that when the liquid material in the storage tank is close to being emptied during use of the mobile liquid injection vehicle, the electric telescopic rod on the blowing and scraping mechanism can be used to drive the scraping ring to move downward, so as to scrape the liquid material adhering to the inner wall of the storage tank with the help of the scraping edge on the scraping ring, and at the same time of scraping the liquid material, the design of the high-pressure air pump, the air cavity and the air jet hole can be used to spray the liquid material scraped on the scraping edge, effectively avoiding the adhesion and residue of the liquid material after scraping on the scraping edge, ensuring the full discharge of the liquid material, because in this scraping method, only one lifting and lowering is needed to achieve the full removal of the stored liquid material, avoiding the tedious operation of heating the storage tank as a whole, saving energy consumption and avoiding the adhesion and waste of liquid material.

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] like Figure 1-Figure 3 As shown, the mobile liquid injection vehicle in this embodiment includes a mobile base 4, and a storage tank 2 is installed on one side of the upper end of the mobile base 4 through three legs 3. The storage tank 2 is mainly used to store liquid media. A cover plate 10 is installed on the top of the storage tank 2. The cover plate 10 is mainly used to cover the storage tank 2. A blowing and scraping mechanism 9 is installed on the cover plate 10, wherein the blowing and scraping mechanism 9 includes three electric telescopic rods 901 installed in a ring shape on the upper end of the cover plate 10, a scraper ring 903 installed together on the telescopic parts of the three electric telescopic rods 901, an annular scraping edge 906 formed on the periphery of the bottom end of the scraper ring 903, an air cavity 904 opened inside the scraper ring 903, an air jet hole 905 opened on the scraper ring 903 and located at the lower side of the air cavity 904, and a high-pressure air pump 902 installed in the middle of the upper end of the cover plate 10 for blowing air into the air cavity 904.

[0033] Among them, when the liquid material in the storage tank 2 is close to being emptied, the electric telescopic rod 901 on the spraying and scraping mechanism 9 can be used to drive the scraper ring 903 to move downward, so that the scraper edge 906 on the scraper ring 903 can be used to scrape off the liquid material adhering to the inner wall of the storage tank 2. At the same time, the design of the high-pressure air pump 902, the air cavity 904 and the air jet hole 905 can be used to spray the liquid material scraped from the scraper edge 906, effectively avoiding the adhesion of the scraped liquid material on the scraper edge 906, thereby ensuring the full discharge of the liquid material.

[0034] like Figure 1-Figure 3 As shown, in this embodiment, the fixed part of the electric telescopic rod 901 is bolted to the cover plate 10, the telescopic part of the electric telescopic rod 901 penetrates the cover plate 10 and is slidably connected to the cover plate 10, and the telescopic part of the electric telescopic rod 901 is bolted to the scraper ring 903. After the electric telescopic rod 901 is started, it is mainly used to realize the up and down lifting of the scraper ring 903, so as to realize the scraping of the adhered material on the inner wall of the storage tank 2 during the up and down lifting of the scraper ring 903. The high-pressure air pump 902 is connected to the air cavity 904 through a telescopic hose, and the air jet hole 905 is opposite to the inner side of the scraping edge 906. After the high-pressure air pump 902 is started, it will inflate the air cavity 904, so that the liquid medium scraped off the scraping edge 906 can be blown off under the action of the high-pressure gas.

[0035] like Figure 2-Figure 4 As shown, in this embodiment, the scraper ring 903 has an inner concave inclined structure located inside the scraper edge 906, and the lower part of the scraper edge 906 contacts the inner wall of the storage tank 2, so that the scraper edge 906 can be used to scrape off the liquid medium on the inner wall of the storage tank 2.

[0036] like Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, a lifting mechanism 8 for realizing convenient lifting of the cover plate 10 is also installed on the outer wall of the storage tank 2. The lifting mechanism 8 includes a fixing ring 801 installed on the outer wall of the storage tank 2, four electric cylinders 802 installed in a ring shape on the upper end of the fixing ring 801, and a boss 803 installed together on the telescopic part of the four electric cylinders 802. The lifting mechanism 8 is mainly used to realize the lifting and lowering of the cover plate 10, so as to add materials into the storage tank 2 and facilitate the cleaning of the storage tank 2. The boss 803 is welded to the cover plate 10, and the boss 803 is an arc-shaped block structure, which can ensure the synchronous lifting and lowering of the boss 803 with the cover plate 10.

[0037] like Figure 1-Figure 3As shown, in this embodiment, a push handle 1 is welded to the upper end of the mobile base 4 located on one side of the storage tank 2. The mobile base 4 is composed of a base plate and self-locking universal wheels installed at the four corners of the bottom end of the base plate. The device can be flexibly moved under the action of the push handle 1. A distribution box 7 is installed on the mobile base 4 on the other side of the storage tank 2 through a bracket 6. The mobile base 4 is located on one side of the bracket 6 and has a liquid pump body 5 for pumping liquid in the storage tank 2 through bolts. The liquid pump body 5 is mainly used for conveniently transporting the liquid medium in the storage tank 2.

[0038] The specific implementation process of this embodiment is as follows: when in use, the cover plate 10 is first lifted with the help of the lifting mechanism 8 so as to fill the storage tank 2 with the liquid material to be transported, and then the mobile liquid injection vehicle is moved to the use position, and the liquid pump body 5 is connected to the external delivery pipeline, and then the liquid pump body 5 is started, and the liquid material in the storage tank 2 can be transported to the designated use position with the help of the liquid pump body 5. During use, when the liquid material in the storage tank 2 is close to being emptied, the electric telescopic rod 901 on the spray scraper mechanism 9 can be used to drive the scraper ring 903 to move downward, so as to scrape the liquid material. The scraping edge 906 on the material ring 903 is used to scrape off the liquid material adhering to the inner wall of the storage tank 2. While scraping off the liquid material, the design of the high-pressure air pump 902, the air cavity 904 and the jet hole 905 can be used to spray the liquid material scraped off the scraping edge 906, thereby effectively avoiding the adhesion and residue of the scraped liquid material on the scraping edge 906, thereby ensuring the full discharge of the liquid material. Since this scraping method only requires one lifting and lowering to achieve the full removal of the stored liquid material, the tedious operation of heating the storage tank 2 as a whole is avoided, thereby saving energy consumption and avoiding the waste of liquid material adhesion.
