Description

Technical Field

[0001] The utility model relates to the field of water tank fixing devices, in particular to a fixing device for a vehicle water circulation system. Background Art

[0002] An on-site inspection vehicle is a special vehicle with an inspection platform. In addition to special inspection instruments, the inspection platform is also equipped with faucets for washing hands, cleaning utensils, flushing test samples, etc., as well as washbasins that are matched with the faucets for collecting sewage. The faucets and washbasins are connected to the municipal pipeline network outside the vehicle through pipes. In actual use, the on-site inspection vehicle will also use sewage tanks and clean water tanks to build a water circulation system. When the pipeline network cannot be connected, a small amount of stored water resources can be used for emergency cleaning. At the same time, it can also reduce the water supply demand of the pipeline network and save a lot of water costs. Among them, the interior of the sewage tank filters foreign matter and impurities through physical barriers. The sewage tank needs to be cleaned after long-term use, but the clean water tank and sewage tank in the current on-site inspection vehicle are mostly welded inside the vehicle, which makes it extremely inconvenient to clean the sewage tank and the cleaning effect is poor. During the cleaning process, sewage will also be flushed onto the floor inside the vehicle. During this period, the floor is wet and slippery, and it is easy to fall. The floor needs to be cleaned later, which increases the workload of the cleaning staff. Utility Model Content

[0027] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods, but this does not constitute any limitation to the present invention.

[0028] Example 1:

[0029] like Figure 1-4 As shown, a fixing device for a vehicle water circulation system includes a wash basin 2, a sewage tank 4 and a clean water tank 7 that can be opened and closed and are located below the wash basin 2. The wash basin 2 is provided with a faucet 1. The drain outlet 21 of the wash basin 2, the sewage tank 4, the clean water tank 7 and the faucet 1 are sequentially connected to form a closed loop. A booster pump 8 is provided between the wash basin 2 and the clean water tank 7. The faucet 1 is connected to the clean water tank 7 through the booster pump 8.

[0030] The wash basin 2 is provided with a shelf 3 for being fixedly connected to the vehicle below, and a supporting plate 33 is fixedly connected to the shelf 3. The clean water tank 7 is provided below the supporting plate 33. The top portion of the supporting plate 33 is provided with a stopper 34 and a top pressure assembly 31 located in the length direction thereof; the stopper 34 is fixedly connected to the supporting plate 33; the top pressure assembly 31 includes a fixing seat 315 fixedly connected to the supporting plate 33, a screw rod 312 extending along the length direction of the supporting plate 33, and a screw rod 312 extending along the length direction of the supporting plate 33. A pressure block 311 is fixedly connected to one end of the adjacent stopper 34, and a screw rod 312 is threadedly connected to the fixing seat 315 in an adjustable manner along its axial direction. The other end of the screw rod 312 is fixedly connected to a handle 314; the sewage tank 4 is clamped between the stopper 34 and the pressure block 311, and a plurality of rollers 32 are provided in the width direction of the support plate 33, which are pressed against the bottom of the sewage tank 4. The rollers 32 all extend along the length direction of the support plate 33 and are all rotatably engaged with the support plate 33.

[0031] The working principle is as follows: the technical solution separates the sewage tank 4 and the clean water tank 7 into the upper and lower layers of the rack 3 through the supporting plate 33 of the rack 3. The sewage tank 4 is matched with the upper side of the clean water tank 7, so that the sewage tank 4 outputs the filtered water to the clean water tank 7 by gravity alone. The block 34 on the supporting plate 33 and the top pressure component 31 clamp the sewage tank 4 on the supporting plate 33. When the sewage tank 4 is to be pressed, the screw rod 312 of the top pressure component 31 is rotated, and the axial movement of the screw rod 312 drives the pressing block 311 to press against the sewage tank 4. The pressure transmitted by the screw rod 312 to the sewage tank in the horizontal direction 4 is fixed, the screw rod 312 is rotated in the opposite direction, and the pressing block 311 is separated from the sewage tank 4 under the drive of the screw rod 312, so that the sewage tank 4 is in a withdrawable state. The roller 32 on the supporting plate 33 supports the bottom of the sewage tank 4 to avoid direct friction between the sewage tank 4 and the supporting plate 33. The contact type between the roller 32 and the sewage tank 4 is line contact. Compared with the surface contact between the sewage tank 4 and the supporting plate 33, the friction resistance is smaller, thereby reducing the relative difficulty of withdrawing the sewage tank 4 from the storage rack 3, so that the sewage tank 4 can be withdrawn to the outside of the vehicle for cleaning, and can also be firmly installed in the vehicle for use with the clean water tank 7.

[0032] In a specific application, the storage rack 3 is provided with four supporting legs, and the bottoms of the supporting legs are welded to the vehicle body.

[0033] Combine Figure 1 and Figure 2 As shown, a further improvement is made in which a nut 313 is sleeved on the screw rod 312 . The nut 313 is threadedly connected to the screw rod 312 in an adjustable manner along the axial direction of the screw rod 312 and abuts against the side surface of the fixing seat 315 .

[0034] In this embodiment, a threaded hole is provided on the fixing seat 315, which is threadedly connected to the screw rod 312. In this embodiment, a nut 313 is provided, and the nut 313 is pressed against the fixing seat 315, and cooperates with the threaded hole to form a double nut 313 structure, so that the screw rod 312 can be self-locked on the fixing seat 315, thereby preventing the screw rod 312 from loosening.

[0035] like Figure 2 As shown, in actual use, the supporting plate 33 is provided with slots corresponding to the plurality of rollers 32 , and the rollers 32 are arranged in the corresponding slots, with the tops of the rollers 32 being higher than the upper surface of the supporting plate 33 .

[0036] like Figure 1 As shown, the specific connection method of this embodiment is that a first hose 9 and a second hose 6 are provided on the sewage tank 4, and the first hose 9 and the second hose 6 are both connected to the sewage tank 4 in a detachable manner and are conductive. The first hose 9 is connected to the drain outlet 21 of the wash basin 2, and the second hose 6 is connected to the clean water tank 7.

[0037] Preferably, the sewage tank 4 is provided with a water inlet 41 detachably connected to the first hose 9 and a water outlet 42 detachably connected to the second hose 6 . The water inlet 41 and the water outlet 42 are both arranged on the same side of the sewage tank 4 and on one side in the width direction of the support plate 33 .

[0038] The water outlet 42 and the water inlet 41 on the sewage tank 4 are arranged on the same side of the sewage tank 4. When the sewage tank 4 is pushed into the storage rack 3 from the width direction of the supporting plate 33, the water outlet 42 and the water inlet 41 of the sewage tank 4 are on one side in the width direction of the supporting plate 33 and are facing the cleaning personnel, which makes it easier for the cleaning personnel to install the pipeline.

[0039] Preferably, a one-way valve 5 is provided on the second hose 6 for preventing backflow of the second hose 6 .

[0040] The setting of the one-way valve 5 prevents the water in the clean water tank 7 from flowing back to the sewage tank 4 through the second hose 6, ensuring that the sewage tank 4 is in a normal state of one-way output.

[0041] Combine Figure 3 and Figure 4 As shown, the specific structure of the sewage tank 4 is that the sewage tank 4 includes a tank cover and a box body sandwiched between a stopper 34 and a top pressure assembly 31, the bottom of the box body is pressed against the tops of a plurality of rollers 32, and the top of the box body is open and detachably connected to the tank cover;

[0042] A partition 45 and a filter assembly are provided in the box body between the water outlet 42 and the water inlet 41. The partition 45 and the filter assembly are arranged horizontally and spaced apart. The edge of the partition 45 is fixedly connected to the bottom and inner wall of the box body. The height of the upper side of the partition 45 is lower than the height of the top edge of the box body. The upper side of the filter assembly is fixedly connected to the inner wall of the box cover, and the edge of the filter assembly abuts the inner wall and bottom of the box body.

[0043] The water inlet 41 and the water outlet 42 are both provided on the box body and located on the upper side of the partition 45 .

[0044] The filtering principle of the sewage tank 4 is that the sewage in the wash basin 2 enters the sewage tank 4 from the water inlet 41 of the sewage tank 4, and first falls into the area on the side of the partition 45 away from the filter component. The sewage gathers in this local area, and the liquid level there continues to rise. Foreign matter and impurities in the sewage also settle to the bottom of the tank over time. The water body and foreign matter and impurities are separated into layers, and the water body on the upper side overflows the top of the partition 45 and flows to the filter component. After physical filtration of the filter component, it flows from the water outlet 42 to the clean water tank 7. When the foreign matter and impurities settled in the sewage tank 4 need to be cleaned, the sewage tank 4 is pumped out for dumping and washing.

[0045] like Figure 1 As shown, in some embodiments, the sewage tank 4 is further provided with a slag discharge port located directly below the water inlet 41. When flushing the inner wall and partition 45 of the sewage tank 4, the slag discharge port is opened and the filter debris is discharged through the slag discharge port to avoid tipping over the box.

[0046] like Figure 4 As shown, the specific structure of the filter assembly is that the filter assembly includes a first filter panel 44 and a second filter panel 43 fixedly connected to the inner wall of the box cover, a partition 45, a first filter panel 44 and a second filter panel 43 are arranged in sequence at intervals, and the edges of the first filter panel 44 and the second filter panel 43 are fixedly connected with a sealing strip 46, which abuts the inner wall and bottom of the box body.

[0047] In a specific implementation, the aperture of the first filter screen plate 44 is larger than the aperture of the second filter screen plate 43 .

[0048] In addition, the clean water tank 7 is provided with a water supply port for connecting to the water supply network, and the sewage tank 4 is provided with a pull ring.

[0049] In this embodiment, in addition to opening the upper cover and pouring water into the clean water tank 7 for water circulation, the water supply port can also be used to connect to the water supply network to directly transport water, thereby improving the convenience and practicality of the clean water tank 7.

[0050] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
