Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the utility model.
As shown in fig. 1 to 3, the device for monitoring the liquid level of the expansion water tank comprises an expansion water tank 1, a liquid level meter 2, a turnover cover 3, a fixing bolt 4, a fixing seat 5, a shockproof sleeve 6, a suction cup 7, a buoy 8, a traction rod 9, a screw rod 10, a transmission gear 11, a transmission shaft 12, a shell 13, a support column 14, a baffle 15, a through hole 16 and an opening 17.
As shown in fig. 1 to 3, an expansion tank liquid level monitoring device comprises a fixed seat 5, a supporting column 14 fixedly connected above the fixed seat 5, a cylindrical shell 13 fixedly connected with the upper end of the supporting column 14, a liquid level meter 2 embedded on the shell 13, a flip 3 arranged above the shell 13, a through hole 16 arranged at the central position of the flip 3, a fixing bolt 4 arranged above the shell 13 and fixedly connected with the flip 3, an expansion tank 1 arranged below the fixed seat 5, a shockproof sleeve 6 arranged below the fixed seat 5 and penetrating through the upper part of the expansion tank 1, a shockproof sleeve 6 which is cylindrical and has a long rectangular opening 17 arranged on the side surface, an opening 17 arranged on one side close to the inner wall of the expansion tank 1, a sucking disc 7 fixedly connected with one side of the shockproof sleeve 6, a monitoring device arranged inside the shell 13 and penetrating through the fixed seat 5, the monitoring device comprises a draw bar 9 which is arranged at the center of the bottom of the shockproof sleeve 6 and the top of which is fixedly connected with the fixed seat 5, a buoy 8 ball which is sleeved on the draw bar 9, a screw rod 10 which is fixedly connected with the upper end of the buoy 8 ball and sleeved with the draw bar 9, a baffle plate 15 which is arranged at the upper end of the buoy 8 ball and sleeved at the lower end of the screw rod 10, a transmission gear 11 which is rotatably matched with the upper thread of the screw rod 10, a transmission shaft 12 of which one end is sleeved on the transmission gear 11, and a liquid level meter 2 which is sleeved at the other end of the transmission shaft 12.
As a preferred scheme, as shown in fig. 1 to 2, the housing 13 is provided with the fixing bolt 4 to fixedly connect the housing 13 and the flip cover 3 together, so that the influence of violent shaking caused by factors such as terrain or brake on a transmission shaft 12 and a transmission gear 11 inside the housing 13 during the driving process of the vehicle is reduced, meanwhile, sundries such as dust inside the vehicle can be prevented from entering the expansion tank 1 through the liquid level monitoring device to form dirt to occupy a space of the cooling liquid, higher accuracy is provided for the liquid level monitoring device to monitor the liquid level height of the cooling liquid, and the suction cup 7 is adsorbed on the inner wall of the expansion tank 1 during installation, so that a firm fixing effect can be provided for the liquid level monitoring device.
When the liquid level in the expansion tank 1 is too high, the through hole 16 arranged in the middle of the flip cover 3 provides an extending channel for the screw 10 in the liquid level monitoring device, so that the screw 10 is prevented from abutting against the top end of the flip cover 3, the situation that the buoy 8 ball is stressed by the screw 10 is avoided, and the buoy 8 ball cannot float out of the liquid level of the cooling liquid, so that wrong liquid level height information is caused.
As shown in fig. 2 to 4, the cylindrical shock-proof sleeve 6 separates the cooling liquid, so that the cooling liquid can only enter the interior of the shock-proof sleeve 6 from the opening 17 on the shock-proof sleeve 6, and the smaller the cross-sectional area of the container is, the lower the liquid shaking amplitude is, so that the liquid level monitoring device can not interfere with the real liquid level height, and even when the vehicle shakes to cause the cooling liquid in the expansion tank 1 to violently roll, the liquid level height in the shock-proof sleeve 6 can be closer to the real liquid level height data under the buffer action of the inner wall of the shock-proof sleeve 6, thereby ensuring the accuracy of the liquid level detecting device.
When the liquid level of the cooling liquid in the expansion water tank 1 changes, the height of the buoy 8 ball can be vertically changed along with the change of the liquid level of the cooling liquid under the traction limit of the traction rod 9 due to the buoyancy provided by the cooling liquid to the buoy 8 ball, and because the total weight of the screw 10 and the baffle 15 is less than the buoyancy of the cooling liquid to the ball of the buoy 8, therefore, the rising or falling of the buoy 8 ball can also drive the screw rod 10 to rise and fall all the time, in the process of rising and falling of the screw rod 10, the transmission gear 11 can also make corresponding rotation due to the transmission action, thereby the pointer on the liquid level meter 2 is changed under the action of the transmission shaft 12, thereby achieving the effect of reflecting the height information of the liquid level in the expansion water tank 1 in real time, even liquid level height is too high simultaneously, also can support fixing base 5 under baffle 15's effect to protection liquid level monitoring device can not break down.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the embodiments, and various equivalent changes can be made to the technical solution of the present invention within the technical idea of the present invention, and these equivalent changes are within the protection scope of the present invention.
