Embodiment
The windshield wiper testing table that the utility model provides as shown in Figure 1, its chief component has: stand 1, stand is provided with the inclination support portion 2 of support glass, the support portion lower limb is equipped with the wiper assembly 3 of glass being scraped water test, the wiper assembly is controlled by automatically controlled part, 2 tops, inclination support portion are provided with the nozzle 4 that is communicated with water supply installation, described water supply installation comprises reserve tank 8, rear pump and output pipe 9, output pipe 9 one ends are connected with nozzle 4, the other end is connected with rear pump, rear pump is communicated with reserve tank 8, simultaneously, also be provided with the windshield wiper assembly is carried out laterally and/or the regulating device 5 of vertically regulating, described regulating device 5 is three kinds of structures, is respectively: first kind, described regulating device comprises that one laterally is installed in the horizontal round conduit 51 on the stand, windshield wiper assembly 3 is by locking with horizontal round conduit regulating block 511 connected vertically, and this structure can be carried out lateral adjustments to windshield wiper assembly 3; Second kind, described regulating device, it comprises that one vertically is installed in the vertical round conduit 52 on the stand, windshield wiper total 3 one-tenth by with 521 lockings of vertical round conduit regulating block connected vertically, this structure can vertically be regulated windshield wiper assembly 3; The third, described regulating device, comprise that one laterally is installed on the stand horizontal circle conduit 51 and and vertically is installed in vertical round conduit 52 on the stand, laterally the circle conduit vertically is connected by regulating block 511 with vertically round conduit, windshield wiper assembly 3 is by regulating block and vertically circle conduit locking, this structure both can be to having passed through to regulate the lateral attitude of windshield wiper assembly 3 on laterally round conduit 51, and also dual regulation is realized in the position of scalable windshield wiper assembly 3 on vertically round conduit 52; Above-mentioned regulating block comprises the square that is provided with circular hole, this circular hole and circle conduit socket, and what be communicated with circular hole extends to outer peripheral slotted eye, and two arm positions of corresponding slotted eye are provided with locking hole.
Further, described windshield wiper testing table also comprises the container structure of a water receiving, and this container structure comprises the water-blocking groove 6 of the glass two edges that are located at the top, support portion, and the water receiving tank between two water-blocking grooves 7, and this water receiving tank 7 is positioned at water-blocking groove 6 belows.
In process of the test, continue have water to spray for ensureing from nozzle, we are provided with flow regulator in output pipe, flow regulator comprises variable valve 10 and/or flow switch 11, variable valve is an ordinary ball valve, and the flow switch string is a kind of senser element that discharge is converted to the switching regulator electric signal in pipeline.When the big what 0.82L/min of the discharge in pipeline flow, sensor output " 1 " switching signal, this signal is input to apparatus control system, realizes the purpose with discharge control after power expands amplification.The little what 0.82L/min of discharge in pipeline flow Hou, sensor output " 0 " switching signal, the work of halt system.
Described water supply installation comprises that also water recovery apparatus 12, one ends are communicated with rear pump, and the other end is communicated with reserve tank 8.The purpose that water recovery apparatus is set is in order to prevent rear pump overload, and its composition mainly contains a three-way connection and ball valve and part connecting tube.Three-way connection one port links to each other with the rear pump delivery outlet, and two ports connect output pipe and ball valve respectively in addition, and ball valve is communicated with reserve tank.Because of the injection flow rate minimum of requirement of experiment is 0.82L/min, the specified jet flow amount of nozzle is 1.5L/min, and the rated output of water pump has reached 3800L/h.When guaranteeing system's operate as normal (flow in the pipeline 〉=0.82L/min), but our manual adjustments ball valve opening makes part water not enter hydraulic pipeline and directly turn back to water tank to a certain degree.The backwater amount is not an explicit value, and its need keep a certain amount of getting final product when system's operate as normal, be unlikely to make system pipeline and excessive to the hydraulic pressure of water pump like this, thereby can improve the serviceable life of water pump and water pipe, joint etc.
In order to improve versatility, the inclination support portion of described windshield wiper testing table comprises the support 21 of fixing glass and the sway brace 22 that is connected supporting bracket, this sway brace 22 is provided with the portait slot bore 221 that is connected with stand, by regulating the angular adjustment of locked position realization to tested glass, thereby the adaptation different automobile types satisfies the adjustment at glass angle of inclination.
The windshield wiper life test rack principle of work that the utility model provides is as follows: the process that simulation is rained, after rear pump started, water sprayed from nozzle 4 by output pipe 9, splashes on the windshield 13, start windshield wiper 3 then, windshield wiper is started working, and water is scraped in the water-blocking groove 6, flows in the water receiving tank 7 again, then by the pipeline reflow tank, finish a circulation, so repeat work, check the windshield wiper life-span; Because the specified water yield that water pump provides is 3800L/h, this is far longer than the requirement of experiment injection flow rate of 820ml/min, so in whole experiment, backwater is carrying out in fact always, injection flow rate is controlled jointly by flow switch and water recovery apparatus, during the system operate as normal, we manually arrive the folding of backwater ball valve suitably size, this folding amount can guarantee the required injection flow rate 〉=820ml/min of experiment on the one hand, can allow water pump come release on the other hand again by backwater, the outlet bore of nozzle only has 1.6mm, and the water outlet bore of water pump has then reached one inch, so the overload pressure that brings water pump because of diminishing suddenly of water pipe bore can be effectively eliminated in being provided with of backwater.When at different vehicle glass, only need the position of adjustment regulating block on horizontal round conduit 51 and vertically round conduit 52 to concern the adjusting that gets final product on the implementation space, in order to improve versatility, also the long slot bore on the adjustable support arm 22 221 gets final product with the stand link position, thereby the adaptation different automobile types satisfies the adjustment at glass angle of inclination.
